Could you please please solve both questions, thank you.
|
1. A 6.30 kg watermelon is dropped from rest from the roof of an 18.0 m-tall building and feels no appreciable air resistance. |
a. Calculate the work done by gravity on the watermelon during its displacement from the roof to the ground.
b. Just before it strikes the ground, what is the watermelon's kinetic energy?
c. Just before it strikes the ground, what is the watermelon's speed?
2. A sled with mass 13.00 kg moves in a straight line on a frictionless horizontal surface. At one point in its path, its speed is 2.00 m/s; after it has traveled a distance 4.00 m beyond this point, its speed is 6.00 m/s.
a. Use the work-energy theorem to find the force acting on the sled, assuming that this force is constant and that it acts in the direction of the sled's motion.
