- A bowling ball traveling with constant speed hits the pins at the end of a bowling lane 16.5 m long. The bowler hears the sound of the ball hitting the pins 2.61 s after the ball is released from his hands. What is the speed of the ball (in m/s), assuming the speed of sound is 340m/s?I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?An express train passes through a station. It enters with an initial velocity of 22.0 m/s and decelerates at a rate of 0.150 m/s² as it goes through. The station in 210.0 m long. How fast is it going when the nose leaves the station?
- A pickup truck is traveling at 30.0 m/s. The driver of the truck applies the brakes and gives the truck a uniform deceleration of 6.50 m/s2² while it travels 20.0 m. What is the speed of the truck in m/s at the end of this distance?A rocket is launched straight up with constant acceleration. Four seconds after liftoff, a bolt falls off the side of the rocket. The bolt hits the ground 7.00s later. What was the rocket's acceleration?A rock is dropped off of a cliff. It takes 2.8s for the rock to reach the bottom. The acceleration due to gravity is 9.81 m/s2. How tall is the cliff?
- A rock is dropped from a 91.0 m tall sky scraper. What is the change in its velocity from the time it is dropped until 1.25 s later? Use 9.80 m/s2 as the acceleration due to gravity. For this problem, let thepositive direction be up, negative down.A juggler throws a bowling pin straight up with an initial speed of 8.2 m/s. How much time elapses until the bowling pin returns to the juggler's hand? 0.84 s 1.68 s O 1.2 s O 2.4 sA police car gets passed by a car traveling at a constant speed of 150.0 km/hr. The police car accelerates from rest at 5.00 m/s2, the moment the two cars are side by side. How long does it take the police officer to catch the car?
- A brick falls from rest from the roof of a tall building. Two seconds later a ball is thrown vertically downward with a velocity 75 m/s at the brick. How far below the roof does the ball hit the brick?A stone is thrown from the top of a building with an initial velocity of 20 m/s downward. The top of the building is 60 m above the ground. How much time elapses between the instant of release and the instant of impact with the ground? 1.0 s 3.5 s 6.1 s 1.6 s 2.0 sAn acorn drops from a tree and takes 1.45 seconds to hit the ground. What height did it fall from?
