An object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x-direction when its x-coordinate is 3.21 cm. If its x-coordinate 2.25 s later is −5.00 cm, what is its acceleration?

1. The cheetah can reach a top speed of 114 km/h. while chasing its prey in a short sprint, a cheetah starts from rests and runs 45 min in a straight line, reaching a final speed of 72 km/h. a. Determine the cheetah's average acceleration during the short sprint, and b. Find its displacement at t= 3.5 s O 4.4m/s2, 27m O 5.6m/s2, 56m O 1.2m/s2, 15m

2. The velocity of a particle is given by v = {14t?î+ (4t + 3)j + 6t³k} m/s, where t is in seconds. If the particle is at the origin when t = 0, determine the magnitude of the particle's acceleration when t = 3 s. Also, what is the x, y, z coordinate position of the particle at this instant?

A car is moving at 18.00[m/s], and comes to a stop in 3.45[s], due to friction acting on the car. Assuming the acceleration is constant, what is the magnitude of the acceleration experienced by the car? Express your answer in m/s2.
