In the middle of the night you are standing a horizontal distance of 14.0 m from the high fence that surrounds the estate of your rich uncle. The top of the fence is 5.00 m above the ground. You have taped an important message to a rock that you want to throw over the fence. The ground is level, and the width of the fence is small enough to be ignored. You throw the rock from a height of 1.60 m above the ground and at an angle of 40.0 ∘above the horizontal.
What minimum initial speed must the rock have as it leaves your hand to clear the top of the fence?
For the initial velocity calculated in the previous part, what horizontal distance beyond the fence will the rock land on the ground?

Assume that the maximum horizontal distance you can throw a baseball (m = 0.145 kg) at an angle of α0 = 45∘ above the horizontal is 25 m. Part A) What is the kinetic energy of the baseball just after it leaves your hand? Ignore air resistance and the small distance the ball is above the ground when it leaves your hand. Take the zero of potential energy to be at the ground. Part B) At the ball's maximum height,...
Standing on a balcony, you throw your keys to a friend standing on the ground below. 1.2 seconds after you release the keys, they have an instantaneous velocity of 14.0 m/s, directed 58° below the horizontal. What initial velocity did you give them? magnitude direction below the horizon
A javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 70 cm as she throws. She releases the javelin 2.0 m above the ground traveling at an angle of 30 ∘ above the horizontal. Top-rated javelin throwers do throw at about a 30 ∘ angle, not the 45 ∘ you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at...
While standing on a bridge 30.0 m above the ground, you drop a stone from rest. When the stone has fallen 5.00 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction.
You launch a projectile with an initial speed of 34.2 m/s from the top of a building 40.0 m above the ground, at an angle of 56.9 degrees above the horizontal. How far from the base of the building does the projectile land on the ground? 109.1 m 120.0 m 163.5 m 130.8 m
QUESTION 5 A ball is kicked with an initial horizontal velocity of 18 m/s from the top of a roof 2.1 m above the ground. What distance will the ball travel horizontally before it hits the ground, in units of meters? Height
