During a very quick stop, a car decelerates at 6.2 m/s2. Assume the forward motion of the car corresponds to a positive direction for the rotation of the tires (and that they do not slip on the pavement). Randomized Variables at = 6.2 m/s2 r = 0.275 m ω0 = 93 rad/s Part (a) What is the angular acceleration of its tires in rad/s2, assuming they have a radius of 0.275 m and do not slip on the pavement? α...

3. A bowling ball of m=7.26kg and v=0.110m is thrown down a bowling alley lane on a cruise ship with initial translational velocity of 3.50m/s. At the moment of the throw the lane is tilted up at an angle of 9.00°and accelerating downward at 2.60 m/s2. The kinetic friction coefficient of the lane is 0.0822 and the length of the lane is 15.1m. Assume the ship remains at the same tilt and acceleration the whole time the bowling ball is...

When an object has positive acceleration, some people assume this means that an object's velocity is pointing in the positive direction and is gaining a larger magnitude. 1) In one paragraph, describe an example of motion in which the acceleration is positive but the assumption above is not true. 2) Justify your answer with some made-up numerical values for initial velocity, final velocity, and time that can be used to compute a positive acceleration.

The pick-up truck in front of you is braking while it is moving towards a red light. The truck is moving to the right (as shown in the figure below). There is a heavy box in the back of the pick-up truck that is not secured by a rope or in contact with any side wall. You observe that the box is not sliding while the truck is braking. The friction force acting on the box is Ff=−114 N. The...
