Question

The displacement of a particle is represented by the following equation s=3t²+7t²+5t+5;where s is in metre and the is in second. The acceleration of particle at the=1s is_
​

Answer 1

Answer:

Explanation:

We need to find acceleration so first differetiating with respect to time gives velocity

v= ds/dt= 6t+14t+5

Further differetiating it gives accleration

a=dv/dt=3+7=10 m/s^2

Dear friend I think your question is like this

s=3t^3+7t^2+5t+8

Answer 2

Answer:

As we know that,

Displacement,S=3t³+7t²+5t+5

on differentiating the displacement with respect to time we get the velocity,

V=ds/dt=9t²+14t+5

On further differentiating the velocity,We get the acceleration..

a=dv/dt=18t+14=18(1)+14=32m/s
