Question

body of mass 1 kg is moving a speed of 10m/s on a level surface. It comes to rest after

travelling a distance of 5m. Calculate force experienced by the object.​

Answer 1

Answer:

10 N in the opposite direction of motion.

Explanation:

Hi friend!

First, let us find acceleration of the block. We can calculate force later by the formula Force = mass x acceleration

To find acceleration, let us use the equation of motion v^2 - u^2 = 2as

Here, u = 10, v = 0 , s =5

-100 = 10 a ==========> a = -10 m/s^2 (or) 10 m/s^2 in the opposite direction of velocity.

Force = mass x acceleration = 1 x 10 = 10 N in the opposite direction of motion.

Hope it helps!!!
