Question

When horizontal force P acts on a cart of mass 20kg it moves with a uniform velocity on a horizontal floor. when a force of 1.2P acts on the cart it moves with an acceleration of 0.05 m/ s2 ,. Find the value of P

Answer 1

Moving with uniform speed means that friction f between the cart and the floor = force applied = P Newton.

a = net force/ mass
0.05 = (1.2 P - f)/20
So P = 5 Newton

Answer 2

Heyaa folk,

The object is moving with a uniform velocity.
Hence,
a = net force / mass
As a = 0.05,
0.05 = ( 1.2 P - f ) / 20
Therefore, P = 5 Newton.

Hope it helps u :)
