A body has an initial velocity of 45km/h and is accelerated uniformly at 2m/s square until its velocity is 72km/h after which is brought to a rest with a uniform retardation. If the total remaining time is 12 seconds; I) sketch the velocity time graph ii) show that the total distance covered can be determined.
A moving beltway at an airport has a speed 1 and a length L. A woman stands on the beltway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the beltway with a speed of 2 relative to the moving beltway. (a) What time interval is required for the woman to travel the distance L? (b) What time interval is required for the man to travel this distance? (c) A second beltway is located next to the first one. It is identical to the first one but moves in the opposite direction at speed 1. Just as the man steps onto the beginning of the beltway and begins to walk at speed relative to his beltway, a child steps on the other end of the adjacent beltway. The child stands at rest relative to this second beltway. How long after stepping on the beltway does the man pass the child?
Try the following experiment away from traffic: where you can do it Safely. With the car VOU are driving moving slowly on a Straight, level road, shift the transmission into neutral and let the car coast. At the moment the car comes to a complete slop, step hard on the ln.ike and notice what you feel. Now repeal I he same experiment on a fairly gentle, uphill slope. Explain the difference in what a pet son tiding in the car feels in the two cases. (Brian Popp suggested the idea for this question.)
A bolt drops from the ceiling of a moving train car that is accelerating northward at a rate of 2.50 m/s2, (a) What is the acceleration of the bolt relative to the train car? (b) What is the acceleration of the bolt relative to the Earth? (c) Describe the trajectory of the bolt as seen by an observer fixed on the Earth.
An ice sled powered by a rocket engine sum from rest on a large frozen lake and accelerates at + 40 ft/s2. After some time t1, the rocket engine is shut down and the sled moves with constant velocity v for a time t2. If the total distance traveled by the sled is 17 500 ft and the total time is 90 s. find (a) the times t1 and t2 and (b) the velocity v. At the 17 500-ft mark, the sled begins to accelerate at 20 ft/s2. (c) What is the final position of the sled when it comes to rest? (d) How long does it take to come to rest?
The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/skm/s . To the crew's great surprise, a Klingon ship is 140 kmkm directly ahead, traveling in the same direction at a mere 30 km/skm/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 6.7 ss . The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant.
You stand on the seat of a chair and then hop off. (a) Duringthe time interval you are in flight down to the floor, theEarth moves toward you with an acceleration of what orderof magnitude? In your solution, explain your logic. Modelthe Earth as a perfectly solid object. (b) The Earth movestoward you through a distance of what order of magnitude?
In his 1865 science fiction novel From the Earth to the Moon, Jules Verne described how three astronauts are shot to the Moon by means of a huge gun. According to Verne, the aluminum capsule containing the astronauts is accelerated by ignition of nitrocellulose to a speed of 11 km/s along the gun barrel’s length of 220 m. (a) In g units, what is the average acceleration of the capsule and astronauts in the gun barrel? (b) Is that acceleration tolerable or deadly to the astronauts? A modern version of such gun-launched spacecraft (although without passengers) has been proposed. In this modern version, called the SHARP (Super High Altitude Research Project) gun, ignition of methane and air shoves a piston along the gun’s tube, compressing hydrogen gas that then launches a rocket. During this launch, the rocket moves 3.5 km and reaches a speed of 7.0 km/s. Once launched, the rocket can be fired to gain additional speed. (c) In g units, what would be the average acceleration of the rocket…
1. If you walk 500 m due North and then 200 m due South,a. What is your total distance covered?b. What is your displacement? 2. A spacecraft traveling at 1200 m/s is uniformly accelerated at the rate of 150 m/s2 by burning itssecond stage rocket. If the rocket burns for 18 seconds, what is the final speed of the craft?
I've been moonwalking for hours, and I'm getting tired. Explain why, as I come to a stop, my velocity is increasing while my speed is decreasing.
Suppose you are in a rocket with no windows, traveling in deep space far from other objects. Without looking outside the rocket or making any contact with the outside world, explain how you could determine whether the rocket is (a) moving forward at a constant 80% of the speed of light and (b) accelerating in the forward direction.
You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 139m/s. How much time does it take for the impulse, which travels at a distance of 1.81m, to reach your brain?
