For a forensics experiment, a student decides to measure the muzzle velocity of the pellets from his BB gun. She points the gun horizontally. On a vertical wall a distance 47.3 m away from the gun, a target is placed. The shots hit the target a vertical distance 0.10 m below the gun's barrel. What is the initial speed of the pellets? Your Answer: units Answer

For a typical foul shot, the rim center is 4.2 m horizontally and 1 meter above where the ball is last touched; ball duration in the air is 1.00 seconds before rim contact.
A plate slides off the edge of a kitchen table with an initial velocity of 3 m/s horizontally. The height of the tabletop above the ground is 4.0 m. (neglect the air resistance) a) what is the range of the projectile? b) What is the velocity (including both the horizontal and vertical components) of the plate just before it hits the ground and shatters into multiple pieces?
A mortar is like a small cannon that launches shells at steep angles. A mortar crew is positioned near the top of a steep hill. Enemy forces are charging up the hill and it is necessary for the crew to spring into action. Angling the mortar at an angle of 0 65.0° (as shown), the crew fires the shell at a muzzle velocity of 148 ft/s. How far d down the hill does the shell strike if the hill d subtends an angle o = 37.0° from the horizontal? Ignore air friction. d = How long will the mortar shell remain in the air? time: S How fast will the shell be traveling when it hits the ground? speed: m/s
Danielle launches a ball off of a platform of height h with velocity vo at an angle 0 above the horizontal. A wall with a ball-sized hole a height H above the floor, with H > h, is a horizontal distance L = 24.0 m away from Danielle. The difference in height between H and h is one-twelfth of L, and the square of the magnitude of the velocity, v, is three-halves of the product gL. H 1 H – h = h 3 L Determine the two values of 0 that ensure the ball passes through the hole. Submit the larger angle as 0, and the smaller angle as 02.
A playground is on the flat roof of a city school, h, - 6.30 m above the street below (see figure). The vertical wall of the building is h= 7.50 m high, to form a 1.2-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of e = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. m/s (b) Find the vertical distance by which the ball clears the wall. (c) Find the horizontal distance from the wall to the point on the roof where the ball lands.

A basketball hoop is 3.05m above the court floor with a rim 0.46m in diameter parallel to the court floor. The free-throw line is 3.7m from the center of the rim. Assume the ball is 0.24m in diameter. The ball was released at a height of 2.5m, and shot with an initial angle of 45o above the horizontal, what is the range speeds that the ball must leave the player’s hands to make the basket without the ball hitting the rim? Over that range of trajectories, how long is the ball in the air for that shot?
