- A car travels 20kph faster than a truck. The car covers 350km in two hours less than the time it takes the truck to travel the same distance. What is the speed of the car? How about the truck?Miles wants to chase a truck that is going at a speed of 25.0 kph, and thus starts accelerating from rest at 4.00 m/s. Caesar, sensing that Miles wants to steal property, and seeing him when he is 100.0 m away from him, rides a police car and starts accelerating at 10.0 m/s. Once Caesar’s car catches Miles, what is the distance traveled by the truck since Caesar started chasing Miles?A man decided to ride his car at 10 kph for the first 5 seconds. He then accelerates at 1 m/s for the next 5 seconds, 2 m/s for the next 5 seconds, 3 m/s2 for the next 5 seconds, and so on and so forth. (a) At what time will he reach a velocity of 60 kph? (b) What is the total distance (m) traveled after he has reached a velocity of 60 kph?
- A man is driving his 4.5 m long automobile at 90 kph when the traffic signal in front of him changes to yellow. He is 55 m. from the intersection when he applies the brakes after 1.5 second reaction time. If the car can decelerates at a rate of 3.2 m/s2, at what velocity will he be moving when he reaches the intersection? If the yellow light is 5 seconds long, where will the man be when the light turns red? Assuming he will continue through at the speed found in part when the light changes to red. How long will the light have red when he clears the intersection having a width of 20m? Answer the problem and show complete solution pleaseA men travels with a speed of 20 ms ¹ for 60 minute. How much distance does he travel ?At one moment aN object in free fall is moving upward with a velocity of 30m/s . How fast would the object move after five seconds?
- A man stands on the top of a 725 m building and drops a coin from the top of the building. How fast is the coin moving when it hits the ground? Use two different physics principles.A bullet shot from a rifle travels at 1000 m/s. What is the elapsed time between when the bullet strikes a target 500 m away, and when the sound of the gunshot reaches the target?A car traveling with an initial velocity of 18 m/s accelerates at a constant rate of 3 m/s squared for 4 seconds. What distance does the car travel during this process? 
- Arthur and Betty start walking toward each other when they are 100 m apart. Arthur has a speed of 3 m/s and Betty has a speed of 2 m/s. Their dog, Spot, starts by Arthur's side at the same time and runs back and forth between them at 5.0 m/s. By the time Arthur and Betty meet, what distance has Spot run? (in meters)You throw an object up with a speed of Voy=1m/s from a height of y=25m. What is the object's final velocity, in meters per second, as it impacts the ground?Car is moving from the rest and reach a velocity of 60 m/s in a time 7sec . Find the acceleration of an object?
