car starts from rest and accelerates at a constant rate until it reaches 90 mi/hr in a distance of 220 ft, at which time the clutch disengaged. The car then slows down to a velocity of 25 mi/hr in an additional distance of 420 ft with a deceleration which is roportional to its velocity. Find the time t for the car to travel the 640 ft.

I fill my tea mug (3.1” diameter and 7.5" tall) to 0.5" from the top and put it in the cup holder of my car without remembering to drink any. During my trip, I accelerate and decelerate smoothly (no hills, bumping, or sloshing). If the tea in the mug is 1" from the top when I get to my destination, the maximum acceleration was about ft/s2
A soccer ball starts from rest and accelerates with an acceleration of 0.385 m/s2 while moving down a 8.50 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 14.75 m, it comes to rest. (a) What is the speed of the ball at the bottom of the first plane (in m/s)? (Round your answer to at least two decimal places.) m/s (b) How long does it take to roll down the first plane (in s)? (c) What is the magnitude of the acceleration along the second plane (in m/s?)? m/s2 (d) What is the ball's speed 8.20 m along the second plane (in m/s)? m/s (e) What If? You change the angles of the two inclines in such a manner that the new acceleration down the first incline is a, new down = 2a initiel down and up the second incline is a, new un x initial up, What is the ball's speed 8.20 m up the second plane (in m/s)? 2 m/s
A care package is dropped out of a cargo plane and lands in the forest. If we assume the care package speed on impact is 54 m/s (123 mph), then what is its acceleration? Assume the trees and snow stops it over a distance of 3.0 m.
A basketball starts from rest and accelerates with an acceleration of 0.395 m/s2 while moving down a 9.25 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 15.00 m, it comes to rest. (a)What is the speed of the ball at the bottom of the first plane (in m/s)?

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with an acceleration of 5.60 m/s2 for 4.20 s, making straight skid marks 62.4 m long, all the way to the tree. With what speed does the car then strike the tree?

A roller coastre car rapidly picks up speed as it roles down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is the average acceleration?
a motorist suddenly notices a stalled car and slams on the brakes, decelerating at the rate of 6.3 meter per second square. unfortunately, this isn't good enough, and a collision ensues. from the damage sustained, police estimate that the car was moving at 18km/h at the time of collision. they also measures skid marks 34m long. (a) how fast was the motorist going when brakes were first applied? (b) how much time was elapsed from the initial braking to the collision?
