Question

The velocity of an object is given by V= 4t³-2t²+5t,Find the acceleration at t=1,Find the distance if v=0 at t=1​

Answer 1

Answer:

Given displacement x=5+3t+2t

2

Differentiating the above equation with respect to time t we get velocity of the body

v=

dt

dx

=3+4t

Now again differentiating the velocity with respect to time we get acceleration

a=

dt

dv

=4
