CP A test rocket starting from rest at point A is launched by accelerating it along a 200.0-m incline at 1.90 m/s 2 ( Fig. F3.43 ). The incline rises at 35.0 C above the horizontal, and at the instant the rocket leaves it, the engines turn off and the rocket is subject to gravity only (ignore air resistance). Find (a) the maximum height above the ground that the rocket reaches, and (b) the rocket’s greatest horizontal range beyond point A . Figure P3.43

A squirrel is launched due west from a height of 10 meters with an initial velocity of 80 meters per second atan angle of 60 degrees above horizontal. A strong wind blowing directly out of the north causes the squirrel toaccelerate south at a rate of 2 m/s^2. All of this takes place in my backyard where acceleration due to gravity is 7 m/s2
(a) With the positive y–axis oriented north, the positive x–axis oriented east, and the positive z–axis up into the sky, findthe vector equation for the path of the squirrel.
(b) Find the time when the squirrel is at her maximum height.
In a volleyball game held in school, Player A at position X serves the ball from a height of 1.3m from the ground, imparting it with an initial velocity at an angle of 50 degrees from the horizontal, He aimed the all to land at point O, 0.5m short to Player B, thus making an ace, Incidentally the Player B is an expert in mind reading. The instant the server hits the ball, Player B started running from rest with a constant acceleration
a. Check whether the ball willclear the 2.42m high net.(answer in meters)b. At what horizontal distance in meters from position Y will Player B intercept the ball, given that he intercepts it at a height of 1.6m?c. What is the acceleration in m/s^2 of Player B
A stone is thrown horizontally from the highest point of a 95 m building and lands 115 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw.
How long is the stone in the air in seconds?
What must have been the initial horizontal component of the velocity, in meters per second?
What is the vertical component of the velocity just before the stone hits the ground, in meters per second?
What is the magnitude of the velocity of the stone just before it hits the ground, in meters per second?
