Question1

1. At one point in a skydive, a falling 99 kg skydiver is encountering air resistance of 442 N. How much does skydiver weigh? 970.2N

2. What is magnitude of the net force acting on this skydiver? 528N

3. At last, what is magnitude of her acceleration?

Question2

The velocity of a solar-powered car as a function of time. The driver accelerates from a stop sign, cruises for 20 s at a constant speed of 60 km/h, and then brakes to come to a stop 40 s after leaving the stop sign.

(a) Calculate the average acceleration during the following time intervals:

(i) t = 0 to t = 10 s (ii) t = 30 s to t = 40 s (iii) t = 10 s to t = 30 s (iv) t = 0 to t = 40 s.

(b) What is instantaneous acceleration at t = 20 s and at t = 35 s?
