- A projectile is launched with an initial velocity of 25.2 m/s at 69.9 degrees with respect to the horizontal. What's the speed of the projectile 1.52s after bein launched. ( assume the speed is measured in m/s)A cannon fires a shell with an initial velocity of 300 m/s at 53.0° above the horizontal. The shell impacts a mountainside 42.0 s after firing. Let the +x-direction be directly ahead of the cannon and the +y-direction be upward. Find the x- and y-coordinates of the shell's impact point, relative to its firing point (in m). x= m y= mA basketball player intends to hit the ball in a basket at a distance8.00 m. The basketball basket is at a height of 3.00 m from the ground and the ball leaves the hand of the player at a height of 1.00 m from the ground. If the ball is thrown from an angle of 45° with the horizontal, what is the initial speed of the ball needed to make the basket?
- A group of collegiate golfers invent a game where they have to hit a golf ball up to the roof of a building that is about 23.76 m tall. The hole is 3.3 m away from the edge of the roof (label this in the figure). The roof is perfectly level all the way across. a) Isabella strikes the ball causing it to launch from the ground with an initial velocity of 22.70 m/s and at an angle of θ = 72.00 . Is it possible for Isabella to make her shot to the roof? Ignore wind resistance for part (a). b) Assuming that Isabella’s shot from part (a) made it to the roof and the shot is line up to go into the hole that is 3.30 m away from the edge of the roof. The golf ball has a mass of 45.93 g, and experiences a friction force of f=0.133 N. If the ball’s speed is larger than 5.90 m/s when at the hole it will be moving too fast and not go in. Will Isabella’s shot go into the hole? Explain why she does make or does not make it in the hole.A group of collegiate golfers invent a game where they have to hit a golf ball up to the roof of a building that is about 23.76 m tall.

Under International Basketball Federation (FIBA) rules, the three-point line is 6.75 meters from the center of the basket. If he will train for three-point shooting, what should be the ball's angle when he shoots the ball if he will try to shoot from a height as high as the basket with an initial velocity of 8.2 m/s? Is it 40°; 50°; 60°? How long would it take for the ball to reach the ring for each of the angles? What is the ball's maximum height for each of the angles? And how fast is the ball's horizontal and vertical initial velocities for each or the angles?A projectile is projected from the origin with a velocity of 47M/S at an angle of 25° above the horizontal.
