A ball of mass 0.5 kg is thrown vertically upwards with an initial velocity of 20 m/s. Find its kinetic energy and potential energy at a height of 10 m.

Assuming μ = 0 ( frictionless surface), we get: F cos 30° = ma A ball of mass 0

Given: Initial velocity (v₀) = 10 m/s, acceleration (a) = 2 m/s², time (t) = 5 s. acceleration (a) = 2 m/s²
