Question

A particle moves in space it coordinate varies as x=2t, y=3t2 and z= x×y. find velocity of particle at t 1s​

Answer 1

Explanation:

The position of a particle moving along x-axis is given by

x=(−2t

3

+3t

2

+5)m

Velocity, v=

dt

dx

=0

−6t

2

+6t=0. . . . . . .(1)

6t(−t+1)=0

−t+1=0

t=1sec

Acceleration, a=

dt

dv

a=−12t+6

a∣

t=1sec

=−12×1+6

a∣

t=1sec

=−6m/s
