- A car is accelerating uniformly as it passes two checkpoints 500 m apart. The car was travelling at 30kph when it passed the first checkpoint. It took the car 10 seconds to reach the secondcheckpoint. What was the car’s acceleration in m/s^2? What was the car’s speed in kph as itpassed the second checkpoint?In the velocity formula, v(t) = 3Nt+C what is the value of the acceleration?You are driving 65.0 miles/hour and you see a police car, so you slow down to 42.5 miles/hour. It takes you 3 seconds to do this. What is your deceleration? (I asked this one before, but someone plugged in -22.5 miles/hr x 2.237 m/s / 1 mile an hour which I didn't understand)
