Question
Find the acceleration of Caren’s bicycle at time t=7.5 minutes. Indicate units of measure
Expert Solution
Step 1
Given:
A car is travelling on a straight road
Time t = 7.5 seconds
To determine:
Acceleration at time t = 7.5 second.
From table:
At time t = 5 seconds
v = 12 feet per second
At t = 20 seconds
v = 20 feet per second.
