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?
The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 2.00 m tall and that the nerve impulse travels at uniform speed.)

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?
Suppose a car is traveling at +21.4 m/s, and the driver sees a traffic light turn red. After 0.511 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 5.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
Rickey Henderson, baseball's record holder for stolen bases, approaches third base. He dives head first, hitting the ground at 6.89 m/s and reaching the base at 5.8 m/s, accelerating at -5.22 m/s/s. Determine the distance Rickey slides across the ground before touching the base.
A person is driving along a straight highway at a speed of 22.0 m/s when the traffic light which is 40.0 m ahead turns yellow. Because of his "reaction time", there is a delay of 0.13 seconds before the man steps on the brake. The car then slows with a deceleration of 4.30 m/s. By how much distance does the driver miss the traffic light line?
A person is driving along a straight highway at a speed of 21.0 m/s when the traffic light which is 43.0 m ahead turns yellow. Because of his reaction time, there's a delay of 0.10s before the man steps on the brakes. The car then slows with a deacceleration of 4.00 m/s^2. By how much distance does the driver miss the traffic light line?
I need help solving this question. A rocket starting from rest rises vertically and accelerates at a constant rate of 13 m/s2 for 7 min. At this point the engine of the rocket accidently fails and completely shuts down. (Neglect air resistance and any variation in the acceleration due to gravity) a) What is the speed of the rocket when the engine shuts down? b) How high is the rocket above the ground at the point where the engine shuts down? c) How much higher will the rocket rise after the engine fails? d) What is the total time of the rocket in air? e) What is the average speed of the rocket for the entire trip?
You know that your friend's car starts at Linden at 1:30 pm and finally arrives at UG at 2:15 pm, but you don't know the route that your friend took. (It is not necessarily the shortest nor the most efficient route and it may have included stops, detours, or side trips.) The straight-line length ("as birds fly") between Linden and UG is 4.71 km, but the car's final odometer reading shows that the car travelled a total distance of 10.50 km from start to finish. What is was the average speed of the car in km/h? (round your answer to two decimal places; DO NOT include units)
The driver of a truck slams on the brakes when he sees a tree blocking the road. The truck slows down uniformly with an acceleration of -5.60 m/s2 for 4.20 s, making skid marks 62.4 m long that end at the tree. With what speed does the truck then strike the tree?
