Physics
A particle's motion is described by x(t)=8t-2t2. (where x is in meters and t is in seconds) f) How fast is the particle moving at t=3s? ______m/s g) How much is it acceleration at t=3s? ______m/s2

Physics
F1 and F2 are two horizontal forces of 70 N each, acting on a wagon. They are at 45° to the x-axis and at right angles to each other. A third force, F3, also 70 N, acts along the positive x-axis. What if, instead, F2 acted in the opposite direction from what is shown? Find...

Physics
A car is traveling at a constant negative velocity of 12.0 m/s. The driver steps on the brakes. The car slows to a stop. The car travels 10.0 m while it is slowing down. What is the magnitude of its acceleration? [HINT: Pay attention to direction.] ________m/s2

Physics
A juggler performs in a room with a ceiling 2.71 m above hand level. What is the maximum upward speed (in m/s) which she can give a ball without letting it hit the ceiling? _________m/s

Physics
An object moves in the +x direction at a speed of 30 m/s. As it passes through the origin, it starts to experience a constant acceleration of 3.7 m/s2 in the -x direction. (b) How much time elapses before the object returns to the origin? _____________s

PHYSICS
A car is moving in the +x direction with the following position equation of motion: x = 5.41(m/s)t - 2.7(m/s^2)t^2. (a) What is the initial velocity of the car? 5.41 m/s (b) What is the acceleration of the car? -5.4 m/s^2 (c) At what time does the car come to rest? __________ ...
