initially at rest is accelerated at a constant rate for 5.0 seconds in the positive x direction. 2. A body (a). If the final speed of the body is 20.0 m/s, what was the body's acceleration? (Spts) (b). Find the position of the body at the end of 5.0 seconds. (5pts)
1) A car is initially moving at 35 m/s is accelerated at 4.0 m/s2 for a period of 7s. The car then travels with the speed after 7s for another 10s. What is the average speed of the car for the 17 s period? a. 63 m/s b. 57 m/s c. 49 m/s d. 35 m/s
An elevator is moving upward with a speed of 11 m/s. Three seconds later, the elevator is still moving upward, but its speed has been reduced to 5.0 m/s. What is the average acceleration of the elevator during the 3.0 s interval? 2.0 m/s2, downward 2.0 m/s2, upward 5.3 m/s2, downward 5.3 m/s?, upward
A car is initially moving at 9.9 m/s in the positive x direction and accelerates at a constant acceleration of 3.4 m/s2 in the positive x direction for 6 seconds. It then immediately has an acceleration of 6.6 m/s2 in the negative x direction. After some time, its velocity is 27.6 m/s in the negative x direction. What is the average velocity for the entire trip in m/s? Indicate the negative x direction by including a negative sign but do...

The elevator experiences a constant downward acceleration of magnitude 3.92 m/s2 for 2.97 s (a) Find the magnitude and direction of the elevator's final velocity. magnitude direction !--Select--# (b) How far did it move during the 2.97 s interval?
8) A particle initially at rest accelerates at 5.0 m/s2. How fast is it moving after 3.2 s? How far 9) A car is moving at 12.0 m/s and then accelerates at 1.5 m/s2 for 10 seconds. What is the 10) A bal is dropped from height H and accelerates downward with acceleration g. In terms of H 11) A rock is thrown straight up in the air at 6.2 m/s and it is released 1.8 m above the ground....
An elevator is initially moving upward at a speed of 13.08 m/s. The elevator experiences a constant downward acceleration of magnitude 4.16 m/s2 for 2.79 s. (a) Find the magnitude and direction of the elevator's final velocity. magnitude direction ---Select--- upward downward none (b) How far did it move during the 2.79 s interval?
8) An object, initially moving with a velocity of 2.0 m is, moves in a straight line with constant acceleration. After traveling a displacement of 5.0 m, it attains a velocity of 3.0 m is. Its acceleration, in m/s2, is: (Please show all work and formula(s) used)
An object is originally moving at 3.5 m/s in the negative x direction with a constant acceleration of 2.4 m/s2 in the negative x direction for 5.1 seconds. Then (immediately) a constant acceleration is applied to in the positive x direction. After some time, the average velocity for the entire trip is 0 m/s., and at that time, the object is moving at 61.2 m/s in the positive x direction. How long was the acceleration applied in the positive x...
