In roller coasters, friction is a force that opposes motion and significantly slows the cars as they move on the track.<span> While it is easy to believe that friction is bad for the ride, it is one of the forces engineers consider in ensuring passengers have a safe ride</span>
The area under the acceleration time graph represents change in velocity
The graph is plotted with acceleration on the vertical axis and time on the horizontal axis. The area under such graph represents change in velocity
Answer:
16.1
Explanation:
165 = 4 + ( 10 ) T
165 = 4 + 10T
Subtract 4 on both sides,
165 - 4 = 10T
161 = 10T
10T = 161
Divide 10 on both sides,
T = 161 / 10
T = 16.1
