Question

Physics help I am so confused

Answer 1

Can you help me?

Answer 2

starting from b)

the speed at the end of a) is 40 ft/s. it accelerates to 80 ft/s in 3.5 seconds.

average acceleration = (final speed - initial speed) / (time) = (80 - 40)/(3.5)

same logic with c). start with the ending speed of b) as your initial speed, let 60 feet be your final speed, and 2.5 seconds be your time.

Answer 3
