m A box rests on top of a flat bed truck. The box has a mass of m = 20 kg. The coefficient of static friction between the box and truck is u, = 0.81 and the coefficient of kinetic friction between the box and truck is u = 0.62. 1) The truck accelerates from rest to v; = 16 m/s in t = 12 s (which is slow enough that the bax will not slide). What is the acceleration of the box? m/s Submit You currently have O submissions for this question. Only 5 submission are allowed. You can make 5 more submissions for this question.

Step 1
The acceleration of an object is defined as the time rate of change of its velocity, i.e.
where v is final velocity and u is the initial velocity.
The frictional force is a contact force that opposes the relative motion between two objects in contact.
The two types of friction are static friction and kinetic friction. Static friction is the one that acts when the frictional force is greater than the applied force. It is given as:
and kinetic friction is the one when the friction force is less than the applied force and the object moves relative to the surface in contact and is given as:
