Astationary 1.67-kg object is struck by a stick. the object experiences a horizontal force given by f = at - bt2, where t is the time in milliseconds from the instant the stick first contacts the object.
if :
a = 1500 n/(ms)
b = 20 n/(ms)2
what is the speed of the object just after it comes away from the stick at t = 2.74 ms?
