A car moving with uniform acceleration covers T 450 meter in first 5 second interval and covers 700 meters in next 5 second interval. The acceleration of the car is

An express train passes through a station. It enters with an initial velocity of 22.0 m/s and decelerates at a rate of 0.150 m/s² as it goes through. The station in 210.0 m long. How fast is it going when the nose leaves the station?

a soldier fires an anti-tank missile at a stationary tank 4850 meters distant. The missile is fired with an initial speed of 28.5 m/s and accelerates with a constant acceleration of 18.6 m/s^2 for 6.42 s. The missile then continues on with a constant speed until it hits its target.  What is the total time that it took the missile to hit the target from the moment it was launched?

A car is traveling along a straight road at a velocity of +39.5 m/s when its engine cuts out. For the next 2.81 seconds, the car slows down, and its average acceleration is a,. For the next 5.65 seconds, the car slows down further, and its average acceleration is ₂. The velocity of the car at the end of the 8.46-second period is +28.6 m/s. The ratio of the average acceleration values is ā,/₂ = 1.78. Find the velocity of the car at the end of the initial 2.81-second interval. 2

A pickup truck is traveling at 30.0 m/s. The driver of the truck applies the brakes and gives the truck a uniform deceleration of 6.50 m/s2² while it travels 20.0 m. What is the speed of the truck in m/s at the end of this distance?

A rocket is launched from the ground such that its net acceleration is 15 m/sec2 when the engine is on. After 10 seconds, the engine cuts off. How high does the rocket go?

A jet plane comes in for a landing with a speed of 120 m/s. The length of the runway is 500 m. From the instant the plane touches the runway,          What is the time interval needed to come to rest (in seconds)?

A speeder travelling at a constant velocity of 40 m/s passes by a police car that is initially at rest.   Soon afterwards, the police officer starts moving towards the speeder with an uniform acceleration of 5.33 m/s2. How long does it take,  in seconds,  for the police officer to catch the speeder?

A car starts from rest, then accelerates at a constant rate over a distance of 80 m. It then immediately decelerates at a constant rate over a distance of 136 m. The entire trip lasts a total duration of 26.0 s. What were the magnitudes of the cars accelerations for the speedup and slowdown stages respectively?

tortoise crawls the entire 1000.0 meters at a speed of 0.20 m/s. The rabbit runs the first 200.0 meters at 2.0 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800.0 meters with an average speed of 3.0 m/s. Who wins the race and by how much time? Get to destination at the same time. Rabbit wins by 47 s Tortoise wing by 47 s O rabbit wins by 2.02 hrs Tortoise wins by2.02 hours
