3. A 180-Ib person jumps out of an airplane with initial upward velocity of 5 ft/s at a height of 3000 ft (assuming the air resistance is proportional to its falling speed). The air resists the body's motion with a force of 2 lb for each ft/s of speed. Assuming the constant gravity is 32 ft/s2. 1. find its velocity v = v(t) 2. find its terminal velocity 3. find the distance of falling x = x(t) 4. find the...

Vi = 8 ft/s 3 ft The girl throws the ball with a horizontal velocity of v, = 8 ft/s. If the coefficient of restitution between the ball and the ground is e = 0.8. determine the velocity of the ball just after it rebounds from the ground and the maximum height to which the ball rises after the first bounce.

A hiker throws a stone from the upper edge of a vertical cliff. The stone's initial velocity is 25.0 m/s directed at 40.0° with the face of the cliff, as shown in the figure. The stone hits the ground 3.75s after being thrown and feels no appreciable air resistance as it falls. (a) What is the height of the cliff (b) How far from the foot of the cliff does the stone land? (c) How fast is the stone moving...

A person throws a ball upward into the air with an initial velocity of 15.0 m/s
A person throws a ball upward into the air with an initial velocity of 15.0 m/s. Calculate the following: a.) how high it goes. b.) how long the ball is in the air before it comes back to his hand. c.) at what time(s) will the ball pass a point 8.00 m. If you got multiples times, are both solutions valid? Why or why not?

Maria throws an apple vertically upward from a height of 1.3 m with an initial velocity of +2.9 m/s. Will the apple reach a friend in a tree house 7.0 m above the ground? The acceleration due to gravity is 9.81 m/s2. 1. No, the apple will reach 5.27136 m below the tree house 2. Yes, the apple will reach 5.27136 m above the tree house 3. No, the apple will reach 1.43117 m below the tree house 4. No,...
If an object is thrown upward with an initial velocity of 64 ft/sec, its height after t sec is given by h = 64t -16t^2
If an object is thrown upward with an initial velocity of 64 ft/sec, its height after t sec is given by h = 64t -16t^2. Find the number of seconds the object is in the air before it hits the ground.
