Question 71

A motorised camera platform moves along a straight, horizontal track. Initially, a resultant force of 90 N causes the platform and its camera to accelerate at 1.5 m s-2.

An additional 15 kg of equipment is then secured to the platform. The motor provides a driving force of 180 N forwards and resistive forces total 30 N backwards.

Calculate the new acceleration of the platform.
