A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.490 m/s. The total mass of the sled, man, and rock is 94.0 kg. The mass of the rock is 0.270 kg and the man can throw it with a speed of 15.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in the direction the sled is moving). m/s Determine the speed of the sled (in m/s) if the man throws the rock directly backward. m/s

A student pushes a 12-kg block on a frictionless, horizontal surface. If the block is initially at rest, what is the speed of the block after the student pushes the block for 5 seconds with an acceleration of 2.0 m/s/s? O 2.0 m/s 6.0 m/s 10 m/s 60 m/s
A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the qun sliding on the ice in the other direction. The bullet's mass is 0.04 kg, and its speed is 305 m/s. If the gun's mass is 2.1 kg, what is its speed (in m/s)? m/s
A child with mass of 16.5 kg stands on the edge of a park bench and leaps into the air. Her initial speed is 2.4 m/s directed at an angle of 30 degrees above the horizontal. After 0.28 seconds what is the horizontal component of her velocity in m/s?
Spaceman Spiff needs to turn his 700 kg rocket and go in the opposite direction to escape the Zoks. He begins by is traveling through space at 3710 m/s when he reverses his course, going in the opposite direction with a speed of 5781 m/s. If his rocket thrusters push his craft with 87000 N of force, how long must he fire his rockets to make the change? 17 s
An object has a velocity (4.69 m/s)i + (-4.4 m/s)j + (4.73 m/s)k. In a time of 5.5 s its velocity becomes (-2.22 m/s)i + (0.00 m/s)j + (4.73 m/s)k. 1) If the mass of the object is 3.31 kg, what is the magnitude of the net force on the object, in N, during the 5.5 s? Assume the acceleration is constant.
A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.530 m/s. The total mass of the sled, man, and rock is 94.5 kg. The mass of the rock is 0.250 kg and the man can throw it with a speed of 14.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in the direction the sled is moving). m/s Determine the speed of the sled (in m/s) if the man throws the rock directly backward.
A 1.4 gram bullet is shot into a tree stump. It enters at a velocity of 341 m/sec and comes to rest after having penetrated the stump in a straight line. It takes 0.00032 sec to come to a stop after striking the stump. What was the force on the bullet during impact? (answer in Newtons)
Your mass is 94.9 kg, and the sled s mass is 21.8 kg. The sled is moving by itself on the ice at 5.71 m/s. You parachute vertically down onto the sled, and land gently. What is the sled s velocity with you now on it? 0.54 m/s 1.39 m/s 1.23 m/s 1.07 m/s

An aging coyote (m = 42.1 kg) cannot run fast enough to catch a roadrunner (m = 16.3 kg). He purchases a set of jet-powered roller skates, which proved a constant horizontal acceleration of 15.2 m/s2. The coyote starts at rest 73.2 m from the edge of a cliff at the instant the roadrunner zips past in the direction of the cliff. Hint: their initial positions at the top of the cliff are the same. a. Determine the minimum constant speed the roadrunner must have to reach the cliff before the coyote. b. At the edge of the cliff, the roadrunner escapes by making a sudden turn, while the coyote continues straight ahead. The coyote’s skates remain horizontal and continue to operate while he is in flight, so his acceleration while he is in the air is (15.2i – 9.80j) m/s2. The cliff is 127 m above the flat floor of the desert. Determine how far from the base of the vertical cliff the coyote lands. c. Determine the components of the coyote’s impulse upon impact.
A rocket sled accelerates to 41 m/s. When the rocket engine stops, the sled skids along its rails. If the coefficient of friction is 0.5 and its mass is 1000 kg, how fast is the sled moving after 2.2 s?
