You stand on the edge of a very tall building with three rocks, which you are going to throw off the edge. You throw the first rock straight outwards, the second rock at an angle 60° above the horizontal, and the third rock 30° below the horizontal. If you throw all three rocks with the same initial speed, which will be moving the fastest when it hits the ground? The first rock The second rock. They will all have the same speed. The third rock

A student at the top of a building of height h throws one ball upward with a speed of i and then throws a second ball downward with the same initial speed i. Just before it reaches the ground, is the final speed of the ball thrown upward (a) larger, (b) smaller, or (c) the same in magnitude, compared with the final speed of the ball thrown downward?
A girl throws a stone from a bridge. Consider the following ways she might throw the stone. The speed of the stone as it leaves her hand is the same in each case, and air resistance is negligible. The stone leaves the hand at the same height for all cases. Case A: Thrown straight up. Case B: Thrown straight down. Case C: Thrown out at an angle of 45° above horizontal. Case D: Thrown straight out horizontally. In which case will the speed of the stone be greatest when it hits the water below? O Case B The speed will be the same in all cases. O Case A Case D Case C
You are diving board over a swimming pool. You are throwing upward a tennis ball at a speed 3 m/s. On its way back down the tennis ball narrowly misses the diving and hits the water below at 15 m/s. The board is about
Standing from the top of the building and I want to hit the root of the big tree below. The height of the building is 90m and the tree is 60m away from the foot of the building. If a throw a stone with a speed of 18 m/s, will I hit the target? If yes explain it. If no at what distance will I miss the target?
A box is thrown upward from a height h = 20 m with an initial speed v = 25m/s that makes an angle of 45 with the horizontal as shown in the figure below. The speed of the box just before touching the ground at point B (va) is equal to: Neglect the effect of air resistance, and use g = 10 m/s2. %3D 45 22.3m/s 35 m/s 50 m/s 32 m/s 28.7 m/s
You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.0 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?
Jenny and Jack throw identical balls off a tall building at the same time. The ground near the building is flat. Jenny throws her ball straight downward. Jack throws his ball downward and outward such that the angle between the initial velocity of the ball and the horizon is 30°. Jack throws the ball with a speed twice that of Jenny's ball. If air resistance is negligible, which ball hits the ground first? Jenny's ball hits first. It is impossible to know from the information given. Jack's ball hits first. They hit at the same time
A girl throws a stone from a bridge. Consider the following ways she might throw the stone. The speed of the stone as it leaves her hand is the same in each case. Case A: Thrown straight up. Case B: Thrown straight down. Case C: Thrown out at an angle of 45° above horizontal. Case D: Thrown straight out horizontally. In which case will the speed of the stone be greatest when it hits the water below? Case A Case B Case C Case D The speed will be the same in all cases. Please explain why the speed will be the same in all cases.
Bart Jumps Springfield Gorge on his skateboard. Springfield Gorge us 50m wide, and Bart has constructed a 1.0 m Hugh ramp inclined at 30° to the horizontal. Air resistance is neglected. Homer had calculated that he can jump the gorge if the ramp is inclined to 45°, and he attains a speed of 20m/s. Will Homer make it? If not, how far short of the other side is he when he drops below the level of the ground?
Joe and Bill throw identical balls vertically upward. Joe throws his ball with an initial speed twice as much as the initial speed of Bill's ball. If there is no air resistance, the maximum height of Joe's ball will be O eight times that of Bill's ball. O two times that of Bill's ball. O equal to that of Bill's ball. None of the given choices O four times that of Bill's ball.
A ball is thrown toward a cliff of height h with a speed of 25m/s arid, an angle of 60? above horizontal. It lands on the edge of the cliff 3.5s later. Part A How high is the cliff? Part B What was the maximum height of the ball? Part C What is the ball's impact speed?
Your brother slides his glass of milk horizontally at a speed m of 0.8 at a frictionless table which is 1.3 m tall. You tried to catch it but missed such that the glass followed a curved path before it crashed on the floor. How far away from the edge of the table did the glass hit the floor?
