A powerful motorcycle can accelerate from 0 to 60.3 mph in 3.14 s. What is the angular acceleration of one of its 180/55ZR-17 (Links to an external site.) tires? 1 inch = 2.54cm (exactly) 1 mph = .4469 m/s Assume 2 significant digits in your final answer
3 A 1350-kg car is to accelerate from rest to a speed of 30.0 m/s in a time of 12.0 s as it climbs a 15° hill. Assuming uniform acceleration, what minimum power is needed to accelerate the car in this way? (Answer in kW)
Cheetahs can accelerate to a speed of 19.5 m/s in 2.45 s and can continue to accelerate to reach a top speed of 29.5 m/s . Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +? direction point in the direction the cheetah runs. Express the cheetah's top speed ?top in miles per hour (mi/h) . ?top= mi/h Starting from a crouched position, how much time ?accel does it take a cheetah...
