can anyone help me with these problems?
1. superwoman is hovering above the ground when a person free-falling goes by her at a terminal velocity of 140km/h. unfortunately the parachute doesnt open. it takes superwoman 1.9 s to realize the person is in distress - what must be her acceleration be if she is to catch the parachutist just before she hits the ground 1000m below?
2. a police car stopped has a speeder pass by at 100km/h. if the police car accelerates at 3.6 m/s^2
a) how long does it take to catcht he speeder
b) how far would the police car have to go before it catches the speeder\c) what would the police's speed be when it catches up?
please help! my test is tomorrow and these 2 problems im stuck on..
