Solution to problems – class 9 – Set 1 Q 18

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 […]

Solution to problems – class 9 – Set 1 Q 22

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 […]
