A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 12.6 m/s, skates by with the puck. After 3.4 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 4.2 m/s?, how long does it take him to catch his opponent?

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?

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 2.00 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.44 m/S?, howlong does it take him to catch his opponent? (a) How long does it take him to catch his opponent?(Assume the player with the puck remains in motion at constant speed.)(b) How far has he traveled in that time?

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 1.20 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.42 m/s2, determine each of the following. (a) How long does it take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.) (b) How far has he traveled in that time?

Initially at rest, John catches a football at the 20 yard line, and immediately begins running forward with an acceleration of 2.3 m/s/s. At the instant John caught the ball, Bill (a player on the other team) happens to be 18.9 m away and he is running directly toward John at a constant 5.7 m/s. If the players run directly toward each other, then how far from the 20 yard line will Bill tackle John?

How long does it take to hit the ground?

A speeder travelling at a constant velocity of 40 m/s passes by a police car that is initially at rest.   Soon afterwards, the police officer starts moving towards the speeder with an uniform acceleration of 5.33 m/s2. How long does it take,  in seconds,  for the police officer to catch the speeder?

1. A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 12.0 m/s, skates by with the puck. After 3.00 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 4.00 m/s, (a) how long does it take him to catch his opponent and (b) how far has he traveled in that time 1. A stone is thrown from the top of a cliff with a velocity of 2.5 m/s and hits the ground 5.5 s later. How high is the cliff? 3. A jogger runs 7.3 km [W], then 4.8 km [S], and finally 2.9 km [E]. The entire trip takes 2.0 h to complete. Calculate the jogger's (a) (b) the total displacement average velocity 4. A plane leaves Toronto and flies with an airspeed of 685 km/h always pointing due East. A wind is blowing from the North at 68 km/h. (a) (b) What is the plane's velocity relative to the ground? What is the plane's displacement from Toronto after flying for 2.5 h? 5. A car is travelling at 26 m/s when it pulls out to pass a…

A cheetah at rest notices a gazelle standing at a distance of 150.0 m. At the same time the gazelle notices the cheetah. The gazelle accelerates at 2.0 m/s2 for 8.0 s, after which it has reached top speed. The cheetah accelerates at 2.5 m/s2 until it has reached its top speed of 115.2 km/h. It can only continue at this speed for 35 s. Will the cheetah catch the gazelle? If so, when and where?

Gretchen runs the first 4.0 km of a race at 5.0 m/s. Then a stiff wind comes up, so she runs the last 1.0 km at only 4.0 m/s. If she later ran the same course again, what constant speed would let her finish in the same time as in the first race?
