1. The velocity of an object moving in a straight line is given by x = (7 + 10t-6t2) m, where t is in seconds. What's the object's velocity at 4 seconds?

2. The velocity of an object moving in a straight line is shown above. If at x = 3.0 m at t= 0 sec. what is the position of the particle at t= 3 seconds?

An object is moving along the axis so that its distance from the origin at time t is given by:

x= 1/6t^4+13/6t^3-10t^2+t

(a) what is the velocity of the object at time t=6 seconds?Ā 

(b) at what time is the acceleration of the object equal to 4m/s^2 ?

Shown below is a graph of velocity versus time for a moving object. The object starts at position x = 0. What is the final position (as measured from x = 0) after it experiences the motion described by the graph, from t = 0 seconds to t = 5 seconds?

An object is moving along a straight line. The graph shows the object's position from the starting point as a function of time.

b) What was the instantaneous velocity of the object at t = 4 s?

c) In which segments(s) of the graph does the object have the highest speed?

d) At which time(s) does the object reverse its direction of motion?
