Solving a problem in physics section 5 point 7 mechanic

7. A ball of mass m = 10 g falls on the horizontal plane with a height h = 27 cm. Find the average force of impact in the following cases: a) the ball and the plane of the steel (absolutely elastic collision); b) the ball plasticine (completely inelastic collision). Consider the same case of impact of the ball on the plane inclined at an angle (α = 30°) Δt = 0,03 s.
