At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is moving converyor belt on which you csan iether stand or walk. Suppose a speed ramp has a length of 117 m and is moving at a speed of 2.1 m/s relative to the ground. In addition, suppose you can cover this distance in 73 s when walking on the ground. If you walk at the same rate with respect to the speed ramp that you walk on the ground, how long does it take for you to travel the 117 m using the speed ramp?

You throw a ball  straight up in the air with a velocity of 60 m/s on a planet where the acceleration due to gravity is 15 m/s^2 A) what is the velocity of the ball after four seconds? B) how long does it take before the ball lands back in your hand?

Derivative as velocity and acceleration. Assume the body as a freely-falling body, with air resistance negligble.  A stone is dropped from rest from a point 125 meters from thegrounf. Find a) it's velocity when it falls on the ground b) the time it takes the stone to reach the point 80 meters above the ground.

A bunch of keys was thrown directly upward by Macoy, who is looking out of the window, to be caught by Len-Len living on a room right above him. Unfortunately, Len-Len wasn't able to catch the keys and therefore the bunch of keys went straight to the ground. If Macoy gave the keys an upward speed of 3 m/s and the keys reached the ground after Macoy threw the keys upward in 4 seconds, c. What is the keys' acceleration when it reached its highest point?d. What is the keys' velocity when it reached its highest point?

A hiker walks 1.50 km north and then 2.70 km east, all in 3.50 hourswhat is the average speed of the hiker

include FBD A stone is thrown upward from the top of the building at an angle of 30owith the horizontal and an initial velocity of 20 m/s. If the height of thebuilding is 45 m, how long will the stone be in flight? What is the totalhorizontal distance traveled by the stone? please solve in paper

At a fireworks display at a shopping mall, a shopper noticed that the sound of an exploding shell arrived 0.20 s after the flash from the explosion. If the speed of sound is 345 m/s, how far away from the person was the explosion?

Hi, I need help with this physcis problem. I've gone over it multiple times and can't firgure it out. Anyway you can help?   A car, initially at rest, accelerates at a constant rate of 2 m/s2 due east (choose east as the positive direction; round your answer to the nearest meter per second; include units)What is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? What is its velocity after 4 seconds? What is its velocity after 5 seconds? What is its velocity after 9 seconds?  If instead a car accelerates at a constant rate of 5 m/s2 due eastWhat is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due westWhat is its velocity after 1 second?

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec.                                           Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.

You are driving your car uphill along a straight road. Of Suddenly, you see a car go through a red light and enter the intersection, just ahead of you. you. You immediately apply your brakes and skid straight to a stop, leaving a 100 ft long mark from the landslide. A policeman observes the whole incident, give the driver of the car a ticket for running a red light. He also gives a ticket to you for exceeding the 30 mph speed limit. When you get home, you read your physics book and you may notice that the coefficient of kinetic friction between the tires and the road was 0.60, and the coefficient of static friction was 0.80. You estimate that the hill makes an angle of about 10° with the horizontal. Check the manual owner and find that your car weighs 2,050 lbs. Are you going to claim the traffic ticket? in the court? Support your argument.         Please type answer not write by hend
