1) If you are initially driving at a speed of 30 km/h with a constant acceleration of 2.0 m/s². Determine how much time, in seconds, it will take you to reach a speed of 60 km/h? 2) You've decided to take a walk for 15 minutes. You went 250 m due north and turned towards the east covering another 150 m before you stopped. Compute your average velocity in meters per second, m/s. 3) A car moves with a constant acceleration along a straight line. If after 3.0 seconds its velocity is 10.0 m/s and after 10.0 seconds the velocity is recorded to be 25.0 m/s, then what is its initial speed?
