A person throws an object into the air with an initial velocity of 3 ft. /s from the ground (i.e. the initial height is zero). How fast is the object travelling when it hits the ground?

Express your answer in SI units and to 3 significant figures. A person throws an object straight up into the air. The object reaches a maximum height of 22.0 meters. How fast was the object travelling when it left their hand? Give your answer in m/s.
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...
An ingot of lead is dropped with an initial velocity of 14 ft/s. When it hits the ground, its temperature has been increased by 0.25 oF. From what height was the ingot dropped (in ft)? Neglect air resistance.
a person throws a ball upward into the air with an initial velocity of 15 m/s calculate a)how high it goes? b)how long the ball is in the air before it comes back ? c)how much time it takes for the ball to reach the maximum height?
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. 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?
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.
if an object is thrown vertically upward with an initial velocity of v, from an original position of s, the height h at any time t is given by: h = -16t^2 + vt + s If an object is thrown vertically upward with an initial velocity of v, from an original position of s, the height h at any time t is given by h16t2 +vt+s (where h and s are in ft, t is in seconds and v...
