A construction worker pulls a five-meter plank up the side of a building under construction by means of a rope tied to one end of the plank (see figure). Assume the opposite end of the plank follows a path perpendicular to the wall of the building and the worker pulls the rope at a rate of 0.28 meter per second. How fast (in m/sec) is the end of the plank sliding along the ground when it is 1.0 meters from the wall of the building? (Round your answer to two decimal places.) Need Help? mysec Food

Jamelle stands at the window of a building 6.2 m above ground level. She throws her keys straight out of the window (horizontally) and hopes that her friend Rochelle, who is standing 10.4 m out from the base of the building, will catch them. Ignoring air resistance and using g = 10m/s^2 for the acceleration due to gravity, find the speed at which Jamelle needs to throw her keys, correct to 1 decimal place.
What is the acceleration , unit SI of the acceleration ?
A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed toward each other along a straight, level track.When they are 950 m apart, each engineer sees the other’s train and applies the brakes.The brakes slow each train at the rate of 1.0 m/s2. Is there a collision? If so, answer yes and give the speed of the red train and the speed of the green train at impact, respectively. If not, answer no and give the separation between the trains when they stop
A plain flies 660mi from Philippines to Thailand in 1.2 HR when travelling with a tail-wind. The return flight against the same wind takes 1.5 he. Find the speed of the plane in still air and the speed of the wind.
A rocket is fired upward with a velocity (v) of 590 feet per second. find how many seconds pass before the rocket reaches the ground (s=0) again. use the quadratic equation s=-16t^2+590t.
A fast food restaurant uses a conveyor belt to send the burgers through a grilling machine. If the grilling machine is 1.1m long and the burgers require 2.5min to cook, how fast must the conveyor belt travel? If the burgers spaced 15cm apart, what is the rate of burger production (in burgers/min)?
Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme acceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s and was brought jarringly back to rest in only 1.40 s. Calculate his (a) acceleration in his direction of motion and (b) acceleration opposite to his direction of motion. Express each in multiples of g (9.80 m/s2) by taking its ratio to the acceleration of gravity.
By analyzing a multiflash photograph of a golfer hitting a golf ball, one finds that the head of the club travels 49.5 cm in 0.0096 s, just before it strikes the ball. Find the approximate instantaneous speed of the club head at the instant of contact.
A horse and a squirrel participate in a race over a 2.00 km long course. The horse travels at a speed of 15.0 m/s and the squirrel can do 3.70 m/s. The horse runs for 1.600 km and then stops to tease the slow-moving squirrel, which eventually passes by. The horse waits for a while after the squirrel passes and then runs toward the finish line. Both animals cross the finish line at the exact same instant. Assume both animals, when moving, move steadily at their respective speeds. (a) How far (in m) is the squirrel from the finish line when the horse resumes the race? (b) For how long in time (in s) was the horse stationary?
Consider a runner moving on the positive direction with an initial Velocity of 6.4 m/s slows down at a constant rate of -0.4 m/s squared over a period of 2 seconds. What distance does she travel during this process?
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. After the rocket's engine turns off at a height of h=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground? Ignore air resistance.
A catapult above an 8m hill launched a ball with 15 m/s initial velocity and hit a moving cart. If the cart was moving 5 m/s towards the hill, how many meters away was the cart from the hill at the moment the ball was launched (initial position of the cart)? a. 18 b. 32 c. 35 d. 15
