Question

The displacement of x a particle varies with time t as x =4t2 -15t + 25.
Find the position, velocity and acceleration of the particle at t=0. When will the velocity of
the particle become zero? Can we call the motion of the particle as one with uniform
acceleration?

Answer 1

Answer:

ANSWER

Given,

x

=t+3

Thus, x=(t+3)

2

Thus, v=

dt

dx

=2t+6

Hence, v varies linearly with t and initial velocity = 6 m/s.
