In this post we will solve harder numerical problems on Vertical motion physics. vertical motion is an interesting chapter in mechanics . Here you get selected problems to solve which will help you to test your understanding.
numerical problems in physics
Problem Statement A car starts from rest and accelerates uniformly over a time of 7 seconds for a distance of 98 m. Determine the acceleration of the car. Solution Distance travelled: S = ut + ½ a t2 As u = 0, the equation becomes S = ½ at2 so, a = 2S/t2 …..(1) t
Problem Statement If a rocket-powered sled is accelerated to a speed of 400 m/s in 2 seconds, then what is the acceleration and what is the distance that the sled travels? Solution Acceleration a = (v-u)/t = (400 – 0)/2 = 200 m/s2 Distance travelled by the sled S = ut + ½ a t2
