Question:
A particle of mass 2kg which starts from rest, moves with an acceleration, in ms -2 , of
a( t ) = -3i + 16cos(20? t )j,
where i and j are the Cartesian unit vectors, and t is time in seconds.
1. What is the x -component, in ms -1 , of the particle's velocity at time t = 2s?
2. What is the magnitude of the force, in newtons, acting on the particle at time t = 2s?
