Question

help me with this one frdzz.​

Answer 1

s = 16t^2

velocity, v = ds/dt = 32t

velocity at 3 sec = 32*3 = 96 ft per sec

velocity at 2.4 sec = 32*2.4 = 76.8 ft per sec

acceleration, a = dv/dt = 32 ft per sec^2

a at 3 sec and 2.4 sec = 32 ft per sec^2

Answer 2

HELLO!

I'm telling you two methods to solve this problem. The first one is using calculus, and the second one is using the Newton's equations of Motion.

Check out the attachment for the solution.

Thanks! :)
