A man with a parachute jumps at a great height from an airplane moving horizontally. After 10 seconds, he opens his parachute. Find his velocity at the end of 15 seconds and his terminal velocity (i.e., the approximate velocity with which he will float to the ground). Assume that the combined weight of man and parachute is 160 pounds, and the force of the air resistance is proportional to the first power of the velocity, equaling 4v when the parachute is closed and 10v when it is opened

Problem 4
A block slides with constant velocity down an inclined plane that has slope angle 0 = 20.0 °. The block is then projected up the same plane with an initial speed vo = 2.10 m/s. (a) How far up the plane will it move before coming to rest? (b) After the block comes to rest, will it slide down the plane again ("yes" or "no")? Give an argument to back your answer. (a) Number i Units (b)
A particle of mass 1.05 kg is subject to a force that is always pointed towards the East but whose magnitude changes linearly with time t. The magnitude of the force is given as F = 4t, and has units of newtons. Let the x-axis point towards the East. Determine the change in x-coordinate in meters of the particle Δx between t = 0 and t = 2.4 if the initial velocity is 17.5 m/s, and pointed in the same direction as the force.

(b) A frictionless incline is 5.00 m long (the distance from the top of the incline to the bottom, measured along the incline). The vertical distance from the top of the incline to the bottom is 1.66 m. A small block is released from rest at the top of the incline and slides down the incline.

(a) Find the velocity of the balloon as a function of time. v(t) (b) What is the furthest distance the balloon could travel? Total distance = meters.
Dont round off thanks.
A small boat is being pushed up a ramp into the back of a flatbed truck. The boat is sitting at the top of the ramp, which is located 1.4 m above the ground. The boaters think the boat is safe there, and begin to walkaway. However, they have neglected the thin layer of ice that has formed on the ramp, which is angled at 30◦ up from the ground. Neglecting the friction between the boat and the ramp, how long do the boaters havebefore the boat reaches the bottom of the ramp?
At a particular instant, a hot air balloon is 48.7m above a horizontal field and descending at a rate of 2.67m/s. At this instant, a girl who is riding in the gondola of the balloon throws a ball with a speed of 14.7m/s with a direction that is horizontal in the frame of the gondola. When the balloon lands on the ground, how far, in meters, is she from where the ball landed? Neglect air resistance.
A projectile is thrown upward from the ground at 76.0° with the horizontal and returns to the ground 2.5 s later. Ignoring air friction (a) How fast was it thrown? (b) How far from its original position did it land? (c) How high above its original position did it go?
