Question 3 A car moving with constant acceleration covers the distance between two points 120 m apart in a time of 8.0 s. Its speed at the second point is 12 m/s. What is the speed of the car at the first point? 0.00 points out of 1.00 Answer Fag question Please enter an answer Check You did not give the correct unit. Question 4 Not complete Points out of 1.00 v Flag question What was the magnitude and direction of the car's constant acceleration? Indicate the direction by the sign. The positive direction is to the right. Answer: Check Question 5 Not complete Points out of 1.00 v Flag question At what position is the car at rest? Assume that the first point is the origin (x = 0 m). If the car is never at rest, answer 0 m. Answer Check

Explanation / Answer

3) from the equation

d = ut+1/2at^2

120 = 12*8+1/2*a*8^2

a = 0.75 m/s^2

v = u+at

v = 12+0.75*8 = 18 m/s

b) a = 0.75 m/s^2

direction is right side

c) here car accelerates so that it never comes to rest

so anser is 0 m
