A skydiver is falling from the sky at a velocity of 50 m/s when they open their parachute they slow down to 5m/s in 3 seconds What is the average acceleration? (I think -15m/s2)
What is the average force of air resistance as the skydiver is slowing?

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
