question

An automobile of mass 50 slugs accelerates from rest. During the first 10 sec, the resultant force acting on it is given by \sumF = F_0 -kt, where F_0 = 200 lb, k = 10 lb/sec, and t is the time in seconds after the start. Find the velocity at the end of 10 sec, and the distance covered in this time.
