Question

a painter is raising himself and the crate on which he stands with an acceleration of 5m/s^2 by a massless rope and pulley arrangement. Mass of the painter is 100kg and that of crate is 50kg.Find the force of contact between painter and crate.

Answer 1

Explanation:

acceleration = 5m/s^2

Mass of painter= 100kg

Mass of crate = 50kg

Total Mass = ( Mass of painter + Mass of crate)

Total Mass= 100kg+50kg

Total Mass = 150kg

Force = mass× acceleration

Force= 150 × 5

Force = 750N
