A particle moving along a straight line has initial velocity v(0) = 1 m/s, and acceleration a(t) = sin(I-t) + cos(t+1) (in m/s?). (a. Find the velocity at time t. (b) Find the average velocity during the time interval [I, 211]. (c) Find the distance traveled during the time interval [1, 2I].

A car is traveling back and forth. Its velocity (in feet per second) after t seconds is given by v(t) = 9−3t.Determine the position of the car after four seconds if s(0) = 0 (where s(t) is the position functionfor the car).a)Find the total distance the car traveled from t = 0 to t = 4

The motion of a particle which moves along the straight line is defined by the relation x(t) = t3 - 9t? + 24t – 8, where x and t are expressed in meters and seconds respectively. Note that the coefficients of t have dimensions accordingly. (a) Determine when the velocity of the particle is zero. (b) Calculate the position vector and distance travelled by the particle when the acceleration is zero. Consider that at the starting point time t = 0 sec. (c) Does the particle move at constant velocity or constant acceleration? Justify your answer.
