A raccoon is sitting on one end of the log and notice that there is an delicious apple just above the other end of the log on the still water as shown on figure. The raccoon starts to walk along the log of 10 meters length at a constant velocity of 0.1 m/s with respect to the log. Neglect its size. The mass of the raccoon is m = 20 kg and the mass of the log is M = 90 kg. Depending on your choice of method, you may answer (b) before (a). You should solve both methods (Center of Mass and Conservation of Momentum). a) As the raccoon is walking, what is the velocity of the log with respect to the shore? b) When the raccoon reaches the opposite end of the log, how far is he horizontally from the apple he desires?

people love to play with balls nowadays especially during quarantine as theres not much to do. lets say we have a ball that hits another ball that is at the rest. after they hit and smash each other, the first ball moves 4m/s on the platform and makes an angle of 25 degrees while the other ball has a speed of 3m/s.. FIND a)get the angle b3tween da d1rection of motion of da second one (ball) and the original direction of motion of da first one. b) find da original sp33d of the first one c)let me ask u this question. is the kinetic energy is being conserving?

Spaceship Malfunction. You and your team get a distress call from another ship indicating that there has been an explosion and their propulsion and navigation systems are now off line. A large piece of their ship has been jettisoned into space, and their life support systems are failing. They need help as soon as possible. You try to track them, but are only able to pick up the piece of the craft that had been projected away from them in the explosion. You look up the make and model of their ship, a Galaxy Explorer 5000 (GE 5000), which has a total mass of 51000 kg. The piece heading in your direction is the ship's storage module, and has a mass of 8500 kg. The GE 5000 was at rest with respect to your ship at the time of the explosion. (a) Assuming you received the distress call 20 minutes before the jettisoned storage module passed by your ship at a speed of 650 m/s, what is the speed of the damaged craft? (b) How far away is the Galaxy Explorer 5000 when its storage module passes by?…

A glass container is knocked off a shelf at a height of 1.4 meters above the floor beside you. It takes you 0.35s to react to the falling object and reach out your hand in an attempt to catch the container. Will you be able to reach the container before it hits the floor?
Planet X was just discovered orbitinga nearby star! It orbits a start that is 6.9 times themass of our sun in a solar system just 31.3 light-years away. The acceleration due to gravity thereis 0.07 g. After making some measurements in lab, you start to daydream about travel to other planets. Your spring gun can launch a projectile with a speed of 3.7 m/s. What would happen if you were tolaunch a projectile at an angle of 32 ° abovehorizontal on Planet X? (a) What maximum height would the projectilereach?(b) How far would the projectile travel before ithit the ground? Assume the projectile lands at the same height it was launched from.
On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.

Super Mario is preparing to jump into a pipe. During motion analysis of his awesome pipe jumping abilities, just prior to his jump, he has flexed his knee. Coordinates of his legs were measured. His hip point is at (3,8), his knee is at (9,4), and his ankle is at (7,-1). The coordinates are measured in cm. a) how long is his thigh? b) how long is his shank (lower leg)? c) What is the angle of his knee joint?
