- A lead ball is dropped into a lake from a diving board 6.20 m above the water. After entering the water, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the water. The ball reaches the bottom 4.80 s after it is released. How deep is the lake?A small mailbag is released from a helicopter that is descending steadily at 1.40 m/s. After 4.00 s, what is the speed of the mailbag? How far is it below the helicopter?A ball is thrown straight up with an initial speed of 15.5 m/s. At what height above its initial position will the ball have one‑half its initial speed? height: m
- During a walk on the Moon, an astronaut accidentally drops his camera over a cliff. It leaves his hands with zero speed, and after 2.00 s it attains a velocity of 7.00 m/s downward. How far has the camera fallen after 4.40 s? in MA teenager climbs a tree that is 40ft tall. Once at the top of the tree he drops a ball that takes 2 seconds to hit the ground. Determine its initial and final speeds.A lead ball is dropped into a lake from a diving board 6.20 m above the water. After entering the water, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the water. The ball reaches the bottom 4.80 s after it is released. How deep is the lake?
- An airplane starts from rest and accelerates at a constant 3.38 m/s2 for 30.32 s before leaving the ground. What is its displacement during this time?A stone is thrown vertically down a well at a speed of 2.7 m s¹. It takes the stone 2.02 s to reach the water at the bottom of the well. Calculate i. the speed with which the stone is falling just before it touches the water. ii. the depth of the well (The acceleration due to gravity is 9.81 m s-2. Air resistance is negligible.)In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.14 m. The mug slides off the counter and strikes the floor 0.80 m from the base of the counter. With what velocity did the mug leave the counter? What was the direction of the mug's velocity just before it hit the floor?
- A model rocket is launched straight upward with an initial speed of 40.0 m/s. It accelerates with a constant upward acceleration of 1.50 m/s2 until its engines stop at an altitude of 180 m. what is the max height reached by rocket? how long after liftoff does the rocket reach its max-height? how long is the rocket in the air?A certain freely falling object, released from rest, requires 1.55 s to travel the last 22.0 m before it hits the ground. (a) Find the velocity of the object when it is 22.0 m above the ground. (Indicate the direction with the sign of your answer. Let the positive direction be upward.) m/s(b) Find the total distance the object travels during the fall. mYou were playing POP POP crackers with your neighbor's kids. To show off your speed, you threw a POP POP cracker at an initial speed of 7.0 m/s downward. The height above ground where you let go of the cracker was about 1.0 m. The cracker popped upon impact with the ground. How long did the kids have between the throw (you let go of the cracker at its initial speed) and the pop (the cracker impacts the ground) to cover their ears and scream? You can assume the final position to be zero. The cracker has negligible amount of air drag. Hint: the cracker has a downward initial velocity. Please include enough significant figures (3 sig. figs.) to ensure your answer is within 5% of the correct answer.
