Question

it x = 20+0.1t^2 . find average acceleration if t is 2 and t is 3

​

Answer 1

Explanation:

Acceleration is defined as rate of change of velocity with respect to time.

so a=

dt

d

v

or a=

dt

d

(20+0.1t

2

)=0+0.1×2×t=0.2t

or a=0.2t which is dependent on time that is it will vary with time so its a non−uniform acceleration.
