A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 4.0 m/s, skates by with the puck. After 1.40 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.10 m/s2, determine each of the following. take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.) (a) How long does S (b) How far has he traveled in that time? m

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 12 m/s, skates by with the puck. After 3.0s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 4.0 m/s, how long does it take him to catch his opponent?
A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times: (Enter your two answers separated by a comma. Round to ONE decimal places.)
how much time would it take you to cover the61-m length of the walkway if, once you get on the walkway, youimmediately turn around and start walking in the opposite direction with a speed of 1.3 m>s relative to the walkway?
By analyzing a multiflash photograph of a golfer hitting a golf ball, one finds that the head of the club travels 49.5 cm in 0.0096 s, just before it strikes the ball. Find the approximate instantaneous speed of the club head at the instant of contact.
A person is standing 350 feet away from a model rocket that is fired straight up into the air at a rate of 15 ft/sec. At what rate is the distance between the person and the rocket increasing 30 seconds after liftoff?
Most important in an investigation of an airplane crash by the U.S. National Transportation Safety Board is the data stored on the airplane’s flight-data recorder, commonly called the “black box” in spite of its orange coloring and reflective tape.The recorder is engineered to withstand a crash with an average deceleration of magnitude 3450 g during a time interval of 6.49 ms. In such a crash, if the recorder and airplane have zero speed at the end of that time interval, what is their speed at the beginning of the interval?
You are a construction worker standing still on 12th Ave N in Fargo, and you watch a minivan drive past at 25 mi/hr eastward. A kid in the back throws a ball at his brother in the front seat at 19 mi/hr. How fast does the ball move, as observed by you? (Positive indicates east, negative indicates west.) ? How fast does the ball move, according to the kid who threw it? If instead the kid in the front seat throws a rock at the kid in the back seat at 19 mi/hr, how fast would you observe the rock to travel?
The sport with the fastest moving ball is jai alai, where measured speeds have reached 303 km/h. If a professional jai alai player faces a ball at that speed and involuntarily blinks, he blacks out the scene for 100 ms. How far does the ball move during the blackout?

In an historical movie, two knights on horseback start from rest 96.9m apart and ride directly toward each other to do battle. Sir George’s acceleration has a magnitude of 0.213m/s^2, while Sir Alfred’s has a magnitude of 0.267 m/s^2. Relative to Sir Georges starting point, where do the knights collide?
An automobile travelling 95km/h overtakes a 1.10km long train traveling in the same direction on a track parallel to the road. If the train’s speed is 75km/h, how long does it take the car to pass it, and how far will the car have travelled in this time?
