Question

Displacement s is related with time t in equation s= 5t square +4t +3. The acceleration is equal to

Answer 1

Answer:

acceleration = 10

Explanation:

we get acceleration on double differentiation..

s=5t^2+4t+3

on on differentiation... we get velocity..,

v=10t+4

we have again differentiation..,

a=10....(uniform acceleration because acceleration didn't depend on time )

Answer 2

s=5t^2+4t+3

v=10t+4

therefore , a=10m/s^2
