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...

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,...
An attacker at the base of a castle wall 3.70 m high throws a rock straight up with speed 7.50 m/s from a height of 1.60 m above the ground. Will the rock reach the top of the wall? If so, what is its speed at the top? If not, what initial speed must it have to reach the top? Find the change in speed of a rock thrown straight down from the top of the wall at an initial...
An attacker at the base of a castle wall 3.55 m high throws a rock straight up with speed 4.50 m/s from a height of 1.60 m above the ground. (a) Will the rock reach the top of the wall? Yes or No (b) If so, what is its speed at the top? If not, what initial speed must it have to reach the top? m/s (c) Find the change in speed of a rock thrown straight down from the...
A ball of mass 0.4 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 16 m/s at angle of 46◦ above the horizontal. The top of the fence is 4 m high. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s^2. Determine the time it takes for...
You throw a 0.5 kg rock upward from your hand (which is 1 m off the ground when the rock leaves it). The rock rises to a maximum height of 2.5 m and then falls past your hand to the ground. From the moment you let it go until the moment just before it lands, what can you say about the work that gravity does on the rock? Group of answer choices a. Gravity does negative net work on the...
wall 3.60 m high throws a rock straight up with speed 7.50 m/s from a height of 1.70 m above the ground. (a) Will the rock reach the top of the wall? Yes No (b) If so, what is its speed at the top? If not, what initial speed must it have to reach the top? m/s ) Find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of...
