A test rocket starting from rest at point A is launched byaccelerating it along a 200.0 m incline at 1.90 m/s2. Theincline rises at 35.0° above the horizontal, and at the instant the rocketleaves it, the engines turn off and the rocket is subject to gravity only(ignore air resistance). Find the maximum height above the ground that the rocket reaches,

In the Olympic shotput event, an athlete throws the shot with an initial speed of 13.0 m/s at a 42.0 ∘ angle from the horizontal. The shot leaves her hand at a height of 1.80 m above the ground.  How far does the shot travel?

i have a question with problem 7

A rescue plane flying horizontally at 252 km/hr in still air spots a survivor in the ocean 180 m directly belowwhen it releases an emergency kit. Air resistance slows the descent such that the kit falls with a constant verticalacceleration of 6.00 m/s2 downward. Due to the shape of the kit, air resistance in the horizontal direction isnegligible. How far from the survivor does the kit land in the water?

To have anv hone of making nar on a hole. a golfer has to hit the next shot over some nearby trees and past a water hazard, whose far side is located-on level ground 100 m away. The ball is hit with an initial speed of 30 m/ at an angle of 45°, allowing it just to clear the trees. Does the ball get past the water hazard? 100 m

A skier leaves the end of a horizontal ski jump at 21.0 m/s and falls through a vertical distance of 3.30 m before landing. (a) Neglecting air resistance, how long does it take the skier to reach the ground? s (b) How far horizontally does the skier travel in the air before landing? m

You can use any coordinate system you like to solve aprojectile motion problem. To demonstrate the truth of this statement, consider a ball thrown off the top of a building witha velocity vS at an angle u with respect to the horizontal. Letthe building be 50.0 m tall, the initial horizontal velocity be9.00 m/s, and the initial vertical velocity be 12.0 m/s. Chooseyour coordinates such that the positive y - axis is upward, thex - axis is to the right, and the origin is at the point where theball is released. (a) With these choices, find the ball’s maximumheight above the ground and the time it takes to reachthe maximum height. (b) Repeat your calculations choosingthe origin at the base of the building.

A golfer hits a shot to the green that is elevated 2.80m above the point where the ball is struck. The ball leaves the club at a speed of 17.6m/s at an angle of 47.0degrees above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.

A ball is thrown from a height h = 15 m above the ground. When the ball leaves with initial speed of 5.0 m/s at an angle of a= 34° below the horizontal. What is the magnitude of the dlisplacement between the launching point and where the ball hits the ground ?

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?
