- A baseball is hit at a height h = 1.00 m and caught at the same height. It travels along side a wall moving up past the top of the wall 1.00 s after it is hit and then down past the top of the wall 4.00 s later at distance D = 62 m further along the wall. Use g = 9.8 m/s/s. What is the magnitude of the initial velocity?A model rocket is fired straight up from the top of a 50-m tall building. The rocket has only enough fuel to burn for 2s. But while the rocket engine is burning fuel, it produces an upward acceleration of 50 m/s^2. After the fuel supply is exhausted, the rocket is in free fall and just misses the edge of a building as it falls back to the ground. Ignoring air resistance, calculate a. the height above the ground and the velocity of the rocket when its fuel runs out. b. the maximum height of the rocket c. the time the rocket is in the air. d. the rocket's velocity the moment before it hits the ground.While exploring the canopy of the rainforest in equatorial South America, Anastasia falls from a branch 35.0 meters high. Exactly 1.3 seconds later Joe falls from the same branch. How high above the ground is Joe when Anastasia splats into the mud below? (the mud is very squishy and nobody is injured)
- While standing on the roof of a building, a boy throws a tennis ball with an initial speed of 15 m / s at an angle of 35 ° below the horizontal. The ball lands on the ground 2.8 s later. How tall, in meters, is the building?Romeo is chucking pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal component of velocity. He is standing at the edge of a rose garden h=10. m below her window and D=8.3 m from the base of the wall. How fast are the pebbles going when they hit her window? (in m/s)You are traveling in a convertible with the top down. The car is moving at a constant velocity of 14.7 m/sdue east along flat ground. You throw a tomato straight upward at a speed of 6.76 m/s. How far has the car moved when you get a chance to catch the tomato?
- a cat is setting at the end of a long hallway. a mouse is running away from the cat , at a constant velocity of 1.58 m/s. whe the mouse is 3.43 meters away from the cat, the cat gets up and accelerates from rest at a constant rate of 1.99 m/s squared to catch the mouse.How much time does it take the cat to catch the mouse? How far does the cat run before catching the mouse?A puma jumps to a height of 2.85 m when leaving the ground at an angle of 42.6°. What is its initial speed (in m/s) as it leaves the ground?A roofer tosses a shingle off a 240.1 m high roof, giving it an initial horizontal velocity of 10 m/s. How far from the building does the shingle land? What is the acceleration of the shingle as it leaves the roof at 2m/s^2?
- A helicopter starts ascending in the sky from the ground and its position is given by y = 5t^2 + 10t. After 10 seconds, a package is dropped out from the helicopter. What is the velocity of the package when it descends to a height of 10 m above the ground.A projectile is launched in the horizontal direction. It travels 2.050m horizontally while it falls 0.450m vertically, and it then strikes the floor. How long is the projectile in the air? What was the original velocity of the projectile?You are traveling in a convertible with the top down.the car is moving at a constant velocity of 16.7m/a, due east along flat ground. You throw a tomato straight upward at a speed of 8.96 m/a. How far has the car moved when you get a chance to catch a tomato?
