A point moves along a straight line. It is uniformly accelerated from rest to 48 fps to the right in 2 sec. The acceleration is then changed to a different constant value such that the displacement for the entire period is 48 ft to the right and the total distance travelled is 192 ft. Determine (a) the total time interval (b) the final velocity.

A car starts from a state of rest and drives along a level, straight road. For the first 30 s, the car speeds up with a constant acceleration of 2.50 m/s 2 , after which it continues at the constant velocity that it has acquired for the next 5.00 minutes, at which time the brakes are applied, and there is an acceleration of -2.2 m/s 2 until the car stops. What is the total displacement of the car from its...

The position function of an object moving along a straight line is given by s = f(t). The average velocity of the object over the time interval [a, b] is the average rate of change of f over [a, b]; its (instantaneous) velocity at t = a is the rate of change of f at a. A ball is thrown straight up with an initial velocity of 144 ft/sec, so that its height (in feet) after t sec is given...
