Question

A car travels along a straight road for 30 seconds starting at time t = 0. Its acceleration in ft/sec? is given by the linear graph below for the time interval [0, 30). Att = 0, the velocity of the

car is 0 and its position is 10.
What is the position of the car when t = 20? You must show your work answer to 3 decimal places. Include units in your answer.

Answer 1

7500 ft

Explanation:

the distance is 250×30=7500 ft

(10)(10)/2 + (20)(20)/2=250ft/sec^2
