- A briefcase (small bag) is thrown at a velocity of 248.5 m/s at a height of 9.7 m. At the same time, a laptop is dropped from the same height from rest. The difference between t the time it takes the briefcase to hit the ground, and t2, the time it takes the dropped :laptop to hit the ground isA motorcyclist heading east through a small town accelerates at a constant 4.9 m/s/s after he leaves the city limits (See figure). At time t = 0 s, he is 5.3 m east of the city-limits signpost, moving east at 27 m/s. Where is he when his velocity is = 37 m/s?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?An egg is thrown horizontally off a roof which is 75 m high with an initial velocity of óm/s.
