A ball is thrown vertically upward with an initial speed of 89 ft/sec from the base A of a cliff with H = 56 ft. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the magnitude of the impact velocity vB. Neglect air resistance and the small horizontal motion of the ball.

Three sleds with mass m are being pulled horizontally on a frictionless horizontal ice surface using ropes. That is, the first sled is pulled by rope, the first sled is attached to the second sled by another rope, and the second sled is attached to the third sled by a third rope. The first sled is being pulled with a force of 190 N. What is the acceleration of the sleds? a) What is the tension in the rope pulling the second sled? b) What is the tension in the rope pulling the third sled? c) Heche d to c blook with mess A ka thot reeto on e frieL:

An arrow is launched from ground level, with an initial speed of 27.2 m/s at an angle of 31.4° above the horizontal. Neglect air resistance, and take upward as the positive direction. a) How much time is needed for the arrow to reach its maximum height, b) what is this maximum heightc) how long does it take to land on the ground againd) how far does it travel right before it lands.

If the stone had been thrown front the cliff too with the same initial speed and the same angle, but above the horizontal, would it’s impact velocity be different?

Chinook salmon can jump out of water with a speed of 7.50 m/s.

The initial speed of a tennis ball is 57.5 m/s and the launch angle is ?i = 16°. Neglect air resistance.Question 1) What is the maximum height, h, of the tennis ball? in mQuestione 2) What is the range, R, of the tennis ball? in m info given: what angle results in the greatest height=90 For this 90° angle, the horizontal component of velocity is zero, so the initial velocity is completely in the vertical direction, resulting in greatest height Kato tries substituting ty,max for t, 0 for yi, and h for yf, and gets h =  vi2 sin2 ?i 2g   When ?i = 90°, sin2 ?i is maximum, so h is maximum what angle results in the maximum horizontal range=45°  I substituted 2vi sin ?i g into the expression for the horizontal component of velocity, (vi cos ?i)t, and got  R =  2vi2 sin ?i cos ?i g when ?i = 45°, 2?i = 90°, and sin 90° = 1, which is its maximum value.

This problem will involve deriving a formula or two for a projectile launched from one height and angle and landing at a different height on Earth. Begin with a projectile launched at angle 0 above horizontal from a height y₁ with initial velocity Vo. The projectile lands at a point with height y₂. These are the given quantities: vo, 0, y₁, y2 and g. Construct formulae for each of the following, as. a function of given quantities the horizontal distance traveled. the maximum height reached. the time taken. the angle of impact. (find the final velocity components first).

You are attacking your enemy’s castle and prepare your catapult to launch a large stone at the castle wall. Asyour clan’s engineer, it is up to you to calculate the correct distance from the wall to fire your catapult. Youknow that the projectile will be launched from the catapult 8.2 m above the ground at a velocity of 40 m/s atan angle of 46◦ above the horizontal, and you want to hit the castle wall 3.0 m above the ground, where theprojectile will do the most damage. How far from the wall should your catapult be positioned?
