a) An athlete threw the ball from the top of a roof 80 m above the ground at 95 mph. Ball, how high is it from the ground when its speed is 120 mph? (1 mile = 1.61 × 10³ m, g=9,8 m/ s², air resistance and friction are neglected)

b) Potential energy of an archer bow U(x) = bx²+ cx³ it's is given by. The spring is stretched according to its balance position the distance is shown by x. When the archer stretches the bow by x, the stretched bow and the archer apply to each other. Find the forces.

c) A furniture carrier pushes a crate ( A crate of 60 kg with a constant velocity v = 2.0 m/s.) on a rough inclined plane. (1.0m height and 2.0m length with kinetic coefficient of friction μk= 0.30.)
