An 900 kg purple pickup truck tows a small 200 kg trailer using a relatively lightweight tow rope. The position of the trailer is given in m and time is in s.
a) What is the magnitude of the net force on the entire system (truck and trailer)?
b) Which is greater, the force of the truck on the trailer or the force of the trailer on the truck?
c) What force on the truck is in the direction of the acceleration of the truck and makes the largest contribution to the net force on the truck?
d) What is magnitude of the net force on the trailer?
e) What is the magnitude of the net force on the truck?
A rocket moves upward, starting from rest with an acceleration of 29.9 m/s2 for 3.31 s. It runs out of fuel at the end of the 3.31 s but does not stop. Evaluate how high does it rise above the ground?
A solid spherical ball of mass 1.21 kg and radius 0.07 m rolls along a smooth, level surface with a speed of 2 m/s. How far up the plane does the ball go
