I assume you have calculus.
a= dv/dt= d(60-60*.7t)/dt=-60*.7^t * ln0.7
I have no idea how to do this question. Would be appreciated if someone help =)
The velocity of a car is given by v(t)=60(1-[0.7]^t), where v is measured in m/s and t is measured in s. Determine the following:
a)What is the acceleration function?
b) What is the accerlation at t=2s?
c)What is the initial velocity?
d)What is the time at which the accleration is 3m/s^2?

Yes, I do have calculus.
So the acceleration function is -60(0.7t)(In0.7)
b) What is the accerlation at t=2s?
-60(0.7(2))(In0.7)= 29.996.
The acceleration would be 29.99 m/s^2?

How do I do part c and d?
