Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

The crate has a mass of 150 kg as shown in
the figure below. It rests on a surface for
which the coefficients of static and kinetic
friction are 0.3 and 0.2 respectively. If the
motor M supplies a cable force of F = (8t2 +
%3|
20) N, where t is in seconds, determine the
power output developed by the motor when t% =
5 seconds. (Use the Kinematic of Particles
equations and the second law of Newton).
