A car driving with a speed of 16 m/s begins braking, coming to rest 45 m after the brakes are first applied. The car's tires have a radius of 38 cm. What is the magnitude of the angular acceleration of the car's tires as it stops?
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,...
A driver in a moving car applies the brakes. The car slows to a final speed of 1.30 m/s over a distance of 40.0 m and a time interval of 8.20 s. The acceleration while braking is approximately constant. (a) What is the car's original speed before braking? What is its acceleration during this time? (The car's initial velocity is in the positive direction. Indicate the direction with the sign of your answer.)

A car with an initial velocity of +4 m/s speeds up at a steady rate to a velocity of +35 m/s in 5 s. (a) What is the car's acceleration? m/s/s (b) If the car maintains this same acceleration for another 3 s, what will be its final velocity? m/s
After an average acceleration of 3.51 m/s2 during 2.81 s, a car reaches a velocity of 14.3 m/s. Find the car's initial velocity. initial velocity: 1.45 m/s
You give a toy car an initial velocity of 1.20 m/s directed up a ramp. The car takes a total of 2.00 s to roll up the ramp and then roll back down again into your hand. Assume that you catch the car at the same point from which you released it, and that the acceleration is constant through the entire motion. (a) Determine the magnitude of the car's acceleration. ________ m/s2 (b) Determine the total distance traveled by the...
A car moves on a flat road with initial velocity vector v1,x = 9.41 m/s and v1,y = -2.37 m/s, then accelerates for 6.53 seconds at an average acceleration of aav,x = -0.102 m/s2 and aav,y = 0.102 m/s2. What are the components of the car's final velocity, v2,x and v2,y? A) v2,x = B) v2,y = C) car's final speed =
