A car increases its speed from 30 mph to 60 mph in 10 seconds. (a) Determine your acceleration, in m / s2 , assuming it is constant. (b) What distance, in meters, does it travel in that time?
3. A car is traveling at 55 MPH? a) What does it mean to say that this car is traveling at 55 MPH? b) How many miles the car will cover in 120 minutes? 4. You are driving at 18 m/s, and a cat runs out in front of your car. You stop rani which takes 3 seconds, and miss the cat. What is your deceleration? 5. A car traveling in a straight line with an initial velocity of 10...
A car accelerates from rest with a constant acceleration of 1.5m/s^2 for 14 seconds . the car then continues traveling at the constant velocity with the speed it achieved after the 14 seconds of acceleration . it travels at this constant velocity for an additional 25 seconds. how far did the car travel during this whole motion?
A car is traveling north along a straight road with a constant speed of 11.2 m/s. In order to pass through an intersection before the traffic light turns red, the driver accelerates forward with a constant magnitude of 2.25 m/s2 for 3.70 s. A)What is v0? B) What is a? C)What is t? D) What is the velocity of the car at the end of the acceleration? E)What is the position of the car at the end of the acceleration?...
Please show work 3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...
1 (a) A car accelerates from rest to a speed of 10.9 m/s in 8.4 seconds. Find the magnitude of the average acceleration. (b) If I accelerate for 5.3 seconds in my car at 2.6 m/s2 when I have an initial velocity of 20.9 m/s, what final velocity do I have? (c) If I apply an acceleration in the opposite direction to my initial velocity for 7.4 seconds of -3.2 m/s2 when I have an initial velocity of +21.6 m/s,...
Problem 3. A car is traveling at a speed of 20 m/s when the driver applies the brakes. The car stops in 5 seconds. How far (in meters) does the car travel in that time? Assume the car's deceleration is constant.

A truck traveling at 50 km/hr approaches a car stopped at a red light. When the truck is 100 m from the car, the light turns green and the car immediately begins to accelerate at 2 m/s2 to a final speed of 100 km/hr. A) • How long does it take for the car to reach its maximum speed? B)During this time, how far does the car travel? C)What is the distance between the truck and the car 20 seconds...
