True or false. when you run around a track at 5km/h, your velocity is constant.

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m
