Pam has a mass of 44.9 kg and she is at rest on smooth, level, frictionless ice. Pam straps on
a rocket pack. The rocket supplies a constant
force for 20.5 m and Pam acquires a speed of
62 m/s.
62 m/s.
What is the magnitude of the force?

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Will you chech and finish these for me, because i am stumped with them.
