a small object moves along the x-axis with acceleration =-(0.0320m/s3)(15.0s-t). at t=0 the object is at x=-14.0m and has velocity =4.50 m/s. what is the x-coordinate of the object when t=10.0s?

An object is moving along the x - axis with uniform acceleration of . At time t=0,X = 5 m and v= 3 m/s.(a) What will be the velocity and the position of the object at time t = 2s?(b) What will be the position of the object when it has velocity of 5 m/s?
An object is at x = 0 at t= 0 and moves along the x axis according to the velocity-time graph in Figure P2.62. (a) What is the object's acceleration between 0 and 4.0 s? (b) What is the object's acceleration between 4.0 s and 9.0 s? (c) What is the object's acceleration between 13.0 s and 18.0 s? (d) At what time(s) is the object moving with the lowest speed? (e) At what time is the object farthest from x= 0? (1) What is the final position x of the object at t = 18.0 s? (g) Through what total distance has the object moved between t= 0 and t=18.0 s?
An object that moves along a straight line has the velocity-versus-time graph shown in the figure below. At time t = 0, the object has position x = 0.
a. At time t = 5 s, is the acceleration of the object positive, negative, or zero?
b. At time t = 8 s, is the object speeding up, slowing down, or moving with constant speed?
c. Write an expression for the position of the object as a function of time.
d. Use your expression from part (c) to determine (if any) at which the object reaches its maximum position.
