Question

Asked Jan 30, 2019

The prompt is in the image attached. The questions I need help are:

a) Evaluate the acceleration at t=1.0 s. Express your answer in m/s^2 in 2 significant figures.

b) Evaluate the acceleration at t=11s. Express your answer in m/s^2 in 2 significant figures.

Thank you!

Step 1

As per the question, the motion is given by the equation

Step 2

Acceleration is given as time rate of change of velocity. hence taking derivative of the velocity equation both side relative to "t", we get

Step 3

(a)

Acceleration at t = 1.0 s is given as

Hence the acceleration comes out to be 3...
