Problem 1: A stationary 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 from the instant the stick first contacts the object. If a = 1.5 x 106 N/(s) and b = 2.0 x 10' N/(s)², what is the speed of the object just after it comes away from the stick at t = 0.00274 s?

Problem 1:
A stationary 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
from the instant the stick first contacts the object. If a = 1.5 x 106 N/(s) and b = 2.0 x 10' N/(s)², what is the speed of the object just
after it comes away from the stick at t = 0.00274 s?
