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....

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how
