As you drive down the road at 18 m/s , you press on the gas pedal and speed up with a uniform acceleration of 1.22 m/s2 for 0.70 s
If the tires on your car have a radius of 33 cm, what is their angular displacement during this period of acceleration?

As you drive down the road at 14 m/s, you press on the gas pedal and speed up with a uniform acceleration of 1.22 m/s^2 for 0.65 s. If the tires on your car have a radius of 33 cm, what is their angular displacement during this period of acceleration? Answer should be in radians.
You are driving down the road at 15 m/s you step on the gas and speed up with uniform acceleration of 2.5 m/s^2 for 0.80 seconds. If your tires have a radius of 34 cm, what is their angular displacement during this period of acceleration?
You drive down the road at 29 m/s (65 mi/h) in a car whose tires have a radius of 37 cm. a) What is the period of rotation of the tires? Express your answer to two significant figures and include appropriate units. b) Through what angle does a tire rotate in one second? Express your answer to two significant figures and include appropriate units.
Your car tire is rotating at 3.4 rev/s when suddenly you press
down hard on the accelerator. After traveling 240 m, the tire's
rotation has increased to 6.6 rev/s. The radius of the tire is 32
cm.
What was the tire's angular acceleration? Give your answer in
rad/s^2.
Express the answer using two significant digits.
The answer I got is, approximately, 0.013405, but, apparently,
it's wrong.

Your car tire is rotating at 3.8 rev/s when suddenly you press down hard on the accelerator. After traveling 260 m the tire's rotation has increased to 5.6 rev/s. The radius of the tire is 32 cm. What was the tire's angular acceleration? Give your answer in rad/s Express your answer using two significant figures rad/s2
A car is initially traveling at 3.3 m/s when the driver steps down hard on the gas pedal resulting in an acceleration of 3.82 m/s2. To one decimal place, what would be the speed of the car be 4.86 seconds later?
Acceleration of gravity is 9.8 m/s
014 10.0 points To test the performance of its tires, a car travels along a perfectly flat (no banking) cir- cular track of radius 143 m. The car increases its speed at uniform rate of d lul at _ = 4.66 m/s2 dt until the tires start to skid. If the tires start to skid when the car reaches a speed of 26 m/s, what is the coefficient of atic friction between the tires...
Driving down the road at a speed of 26.6 m/s, you suddenly notice a fallen tree blocking the road a distance of 57.9 m ahead of you. You step on the brake pedal and decelerate at a constant rate. What must the magnitude of your acceleration be so that you will come to a stop 7.6 m in front of the tree?
Driving down the road at a speed of 40.0 m/s, you suddenly notice a fallen tree blocking the road a distance of 88.4 m ahead of you. You step on the brake pedal and decelerate at a constant rate. What must the magnitude of your acceleration be so that you will come to a stop 5.9 m in front of the tree?
Your friend John intends to drive your 1000-kg car at a speed of 25 m/s around a horizontal curve whose radius is 100 m. You know that the coefficient of static friction between the tires and the road is .350. Will John be able to drive your car around the 100 m radius? Explain you answer.
