The acceleration of a particle is given by a - 2t - 17, where a is in meters per second squared and tis in seconds. Determine the velocity and displacement as functions of time. The initial displacement at t= 0 is so = -2 m, and the initial velocity is vo = 4 m/s. Once you have determined the functions of time, answer the questions. Questions: When t = 5.9 s, m i m/s m/s?

A particle moves along a straight line with an acceleration described by the equation. a = 3t2 + 2t + 4 in which acceleration 'a' is in m/s and time t is in seconds. It is observed that velocity of the particle is 12 m/s after 4 seconds and displacement of the particle is 8 m at the end of 4 seconds. Determine the Velocity of the particle after 10 seconds.

During a race, you are running at a speed of 4.50 m/s. You want to pass a slowerrunner, so you increase your speed steadily (that is, with constant acceleration) to5.75 m/s over a time period of 3.00 s. What was your acceleration over this timeperiod, and what distance did you travel between when you started and ended theacceleration? When taking off, a commercial airliner starts from rest and attains a velocity of81.0 m/s over a distance of 1.50 km. Assuming that it accelerates at a constantrate, what is this rate of acceleration?
