Hassan is sitting in a car moving along the highway. He reads 90km/h on the speedometer 4. a. b. c. What does the reading of the speedometer indicates? Convert the speed given into m/s 10 minutes later the speed of the car was still 90 km/h. We plotted a graph showing the variation of speed with time i. Is the speed of the car constant? Increasing or decreasing? ii. What is the type of motion in this case? Speed d....

A car and a train move together along straight, parallel paths with the same constant cruising speed v0. At t=0 the car driver notices a red light ahead and slows down with constant acceleration −a0. Just as the car comes to a full stop, the light immediately turns green, and the car then accelerates back to its original speed v0 with constant acceleration a0. During the same time interval, the train continues to travel at the constant speed v0. How...
