5. A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver accelerates with constant accelerationalong the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 22m/s when it reaches theend of the 120-m-long ramp(a) What is the acceleration of the car?(b) How much time does it take the car to travel the length of the ramp?(c) The traffic on the freeway is moving at a constant speed of 20 m/s. What distance does the traffic travel while the car is movingthe length of the ramp?а

Given:Initial velocity of the car = 0 m/sFinal velocity of the car = 22 m/sLength of the ramp = 120…

4.A cruise ship can accelerate at 0.01 m/s 2 , if it starts from rest how long does it take toreach a speed of 25 km/h? How long would it take if it started from a speed of 2.0 m/s? 5.A runner can maintain a constant acceleration of 1.1 m/s 2 for 8.5 seconds. Whatdistance could the runner cover in that time if starting from rest?
Cheetahs have a top speed of 120 km/hr and can accelerate at a constant rate of 9.5 m/s^2. How long would it take a cheetah, stalking its prey at 4.2 m/s, to reach its top speed?
Accelerating from rest, a top fuel race car can reach 338.2 mph (148.9 m/s), a record established in 2003, at the end of a quarter mile. How long does it take the race car to complete a quarter-mile run from a standing start?
A sprinter accelerates from rest to a top speed with an acceleration whose magnitude is 3.70 m/s2. After achieving top speed, he runs the remainder of the race without speeding up or slowing down. The total race is fifty meters long. If the total race is run in 7.00 s, how far does he run during the acceleration phase?
6. A sports car must achieve a velocity of 100m.s after passing the entry tollgate of an expressway. If the driver can do it after travelling 200m, what must his car's acceleration?
In 1967, New Zealander Burt Munro set the world recordfor an Indian motorcycle, on the Bonneville Salt Flats in Utah,with a maximum speed of 183.58 mi/h. The one-way coursewas 5.00 mi long. Acceleration rates are often described bythe time it takes to reach 60.0 mi/h from rest. If this time was4.00 s, and Burt accelerated at this rate until he reached hismaximum speed, how long did it take Burt to complete thecourse?
At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.05 m/s2 . At the same instant a truck, traveling with a constant speed of 25.0 m/s , overtakes and passes the car. How far beyond its starting point does the car overtake the truck?
