Do you guys know what would be the curve looks like in the acceleration versus velocity graph? (including the air resistance when an object is falling) Thank you!

Why it is easier to stop a tennis ball than a cricket ball moving with the same speed?

What must be your average speed in order to travel 200 km in 3.25 h? A bird can fly 26 km/h. How long does it take to fly 19 km? If you are driving 116 km/h along a straight road and you look to the side for 3.0 s, how far do you travel during this inattentive period? A horse canters away...

A bolt comes loose from the bottom of an elevator that is moving upward at a speed of 6.50 m/s. The bolt reaches the bottom of the elevator shaft in 4.55 s. How high up was the elevator when the bolt came loose?

In which case is the average velocity equal to the instantaneous velocity? Why?
