Two projectiles are launched from two different heights, as shown in the figure. Projectile A, on the left, is launched from a 30 m building, with an initial speed of 50 m/s in a horizontal direction. Projectile B, at right, it is launched from a building 100 m from the other building and from a height of 15 m. It is also known that the Projectile B is launched at an angle of 135° with respect to the horizontal, with unknown initial velocity. Find: The position where both projectiles crash into each other. 30m دهاشه 100m 2-16) 15m 135

You can use any coordinate system you like in order to solve a projectile motion problem. To demonstrate the truth of this statement, consider a ball thrown off the top of a building with a velocity v at an angle 0 with respect to the horizontal. Let the building be 54.0 m tall, the initial horizontal velocity be 9.10 m/s, and the initial vertical velocity be 10.5 m/s. Choose your coordinates such that the positive y-axis is upward, and the x-axis is to the right, and the origin is at the point where the ball is released. (a) With these choices, find the ball's maximum height above the ground and the time it takes to reach the maximum height. maximum height above ground time to reach maximum height (b) Repeat your calculations choosing the origin at the base of the building. maximum height above ground time to reach maximum height

A cannonball is launched diagonally with an initial horizontal velocity of 50.0m/s and an initial vertical velocity of 30.0Om/s. Label the hypotenuse, opposite side and adjacent side, and determine all unknowns. initial velocity: m/s initial horizontal velocity: m/s initial vertical velocity: m/s At what angle (0) was the cannonball launched?

Find: a) The initial velocity with which projectile B is launched. b) The time elapsed from when the projectiles are launched to when they crash into each other. 30m √(4) 100m 2-18) 15m 135°

Snowballs are thrown with a speed of 19 m/s from a roof 7.0 m above the ground. Snowball A is thrown horizontally; snowball B is thrown in a direction 35° above the horizontal. Find the direction of motion (that is, the angle of the velocity vector) of each of the two snowballs just before they land.

In 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77 m. What was the initial speed of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus, 38° will give a longer range than 45° in the shot put.)
