QUESTION 8 OK, same sort of track, but now with d = 2.10 m. Now suppose the blocks starts on the track at x = 4.76 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? A 8.30 m/s B 14.55 m/s C 10.29 m/s D 17.39 m/s
The work required by Neymar to push a box of soccer balls on a horizontal, frictionless floor to accelerate it from a speed of zero to v is W1. The work required by Neymar to accelerate the box of soccer balls on the same floor, from v to 2v is W2. The ratio of W2 to W1 is The correct answer is 3 but I don't know how they got to that answer

A penguin slides down an icy incline on his stomach, as shown in the diagram below. The coefficient of kinetic friction between the incline and the penguin's stomach is 0.15. The angle of the incline is 0 = 25 degrees. The total distance down the incline is 25 meters. The penguin gets a running start so his speed is 2.5 m/s when he begins to slide down the incline. What is the penguin's speed when he reaches the bottom of the incline? Hint: use Newton's 2nd law to calculate the acceleration of the penguin on the incline, then use kinematic equations to calculate the speed of the penguin when he reaches the bottom. 2.5 m/s 25 m 25°
A 51.2 kg sled coasts down a hill, starting from rest. The hill is inclined at an angle of 20.8 degrees with respect to the horizontal and has a height of 7.25 m. The sled's blades have recently been greased so that the sled slides down the hill without friction. What is the final speed of the sled (in m/s) just as it reaches the bottom of the hill? Use g = 9.81 m/s2.
