Question

A BODY OF MASS 10 KG IS MOVING WITH A VELOCITY OF 25M/S IS STOOPED WITH A UNIFORM FORCE AT 50M ? CALCULATE THE FORCE

Answer 1

the force = -62.5N. ..........

Answer 2

Explanation:

Given - Mass (m) = 10 Kg

Velocity (u) = 25m/s

Velocity (v) = 0 m/s

Distance (S) = 50 m

To Find, Force.

$force \: = m \times a$

$v ^{2} = u {}^{2} + 2as$

$0 = {25}^{2} + 2a(50)$

$- 625 = 100a$

$0 = 625 + 100a$

-625 = 100a

-625/100 = a

a = - 6.24m/s^2

Force = 10 * (-6.25)

F = -62.5 N
