A car travels 80 km in 1.5 hours and 40km in the next 0.5 hour. What is its average speed?
A bus, initially at rest, accelerates to a velocity of 15 m/s in 3 s. It then continues to accelerate at the same constant rate for an additional 7 s. What is the total distance the bus has traveled?
Which velocity-time graph represents a body moving with uniform acceleration?
A stone is thrown vertically upwards with a velocity of 25 m/s. How long does it take to reach its highest point, and what maximum height does it reach? (Take g = 10 m/s²)
A car is traveling at a constant velocity of 20 m/s. At the moment the car passes a stationary truck, the truck begins to accelerate from rest at a constant rate of 2.5 m/s². How long does it take for the truck to catch up to the car, and what is the distance traveled at that point?
A car's motion is described by a velocity-time graph. The car starts from rest and accelerates uniformly to a velocity of 10 m/s in 5 s. It then travels at this constant velocity for another 5 s. Finally, it decelerates uniformly to a stop in 5 s. What is the car's total displacement during the entire 15 s journey?
From a velocity-time graph, the area under the line represents:
A car moves at 20 m/s for 5 s, then at 30 m/s for 5 s. What is the average speed over the 10 s?
The velocity of a car at different times is recorded in the table below. Use the data to calculate the car’s average acceleration and total displacement after 8 seconds.
A train is moving at a constant speed of 15 m/s. A passenger standing on the platform begins to run from rest at the exact moment the front of the train passes him. If the passenger accelerates uniformly at 1.5 m/s², how long does it take before the passenger catches up with the back of the train, which is 120 m long?
