Question

The displacement of the body x(in meters) varies with time t (in sec) as
x= 3t2+2t+3 meter. find the velocity at,t=1?​

Answer 1

Answer:

8m/s

Explanation:

We know that dx/dt = velocity

•°• dx/dt = d(3t²+2t+3) /dt

=> 6t + 2 + 0

=> 6t+2

We have to find velocity at t = 1

•°• dx/dt = V = 6*1+2 = 8meter/sec

velocity of body = 8m/sec
