Q1
A red car moves at 72 km/hr. As the red car passes by a stationary blue car, the blue
car starts to move at a constant acceleration to catch the red car after 8 seconds. What
is the acceleration of the blue car? How far from the starting point is the meeting
point?
Q2
Find the velocity
x& and the position x as functions of the time t for a particle of mass
m
, which starts from rest at x = 0 and t = 0, subject to the force functions Fx = mc t ,
where c is a positive constant.
Q3
Find the position x at time t = 9 s for a particle of mass 2 kg, which starts from rest at
x
= 0 and t = 0, subject to the force function Fx = 30 t
(Answer is x= 972 m)
