Question

Scenario

Andrea is driving her car and getting on Interstate 70. She is traveling 10 m/s at the beginning of the
highway on-ramp and accelerates to 30 m/s at the end of the on-ramp. It takes her 4 seconds to get to
full speed
What is Andrea's acceleration to get on the on-ramp ?

Answer 1

5m/s/s

Step-by-step explanation:

The units for velocity is m/s.

The units for acceleration is m/s/s

So, Determine the change in velocity and divide it by the time that change took place.

(30m/s - 10m/s)/4s = 20m/s/(4s) = 5m/s/s
