Question

A particle moves in a straight line. It is initially at rest at the origin. The acceleration of the particle is given by x(t)= 1/3cos3t. Then find the velocity at time t.

Answer 1

Answer:

Explanation:

for this you have to know diffrentiation by diffrentiation this is so easy

dx/dt=v

=d(1/3cos3t)/dt

=1/3d(cos3t)/dt

=1/3*-sin3t

=-1/3sin3t
