A scooter rider begins at 4.0 m/s, then is accelerated with a constant acceleration of 5.0 m/s2 for 5.0 s. Next, the rider hit the brakes and slows down to a stop with a deceleration of 6.0 m/s2. How far did the scooter travel in the complete motion?

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Abicycle slows down when the rider applies the brakes. what type of energy transformation is involved in this example? a. kinetic energy into heat energy b. heat energy into potential energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy
