Question

displacement of a body is given by the relation S=-2t^2+30t+10. Determine the initial velocity and acceleration of the body​

Answer 1

Answer:

Correct option is

A

4 units

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
