Differential Equations:

A 77 kg sprinter jumps over a hurdle that is 0.8 m above the ground. The sprinter's initial velocity is 4 m/sec. If the air resistance is 7v, determine the velocity of the sprinter when he hits the ground.

Note: Use g = 9.81 m/sec2 and apply Newton's second law for a falling object mv' = mg - bv

An object of mass 120 kg is released from rest 480000 m above the ground and allowed to fall under the influence of gravity. Assume the gravitational force is constant, with g=9.8 m/sec2 , and the force due to air resistance is proportional to the velocity of the object with proportionality constant k= 3 kg/sec. Approximate the speed (in m/sec) of the object when it strikes the ground.

An object of mass 5 kg is released from rest 24525 m above the ground and allowed to fall under the influence of gravity. Assume the gravitational force is constant, with g=9.8 m/sec2 , and the force due to air resistance is proportional to the velocity of the object with proportionality constant k= 1 kg/sec. Approximate when (in seconds) the object will strike the ground.

Solve the following exercise by applying differential equations: A person weighing 67 kg falls from a building measuring 40m with an initial speed of 3m / sec. Let's suppose: The air resistance is proportional to the speed of the body. The limit speed at which it can fall is 40 m / sec. Find: a) the expression of the velocity of the object in a time t, b) the expression for the position of the body at a time t...
