 Chapter 2 Practice Problems

 1

A car decelerates from a speed of 40 km/h to rest in seconds. What is the magnitude of the acceleration in m/s2 to one decimal place?

 2

A car decelerates from a speed of 50 m/s to rest in meters. What is the magnitude of its acceleration to one decimal place?

 3

How long to the nearest second does it take a car accelerating from rest at 2.5 m/s^2 to cover a distance of meters?

 4

A car travelling at 36 m/s passes a policeman who immediately accelerates at m/s^2 from rest in pursuit. To the nearest second how long does it take the policeman to catch the speeder?

 5

A stone falls off a tall building and hits the ground seconds later. To the nearest meter how high was the building?

 6

Standing on the top ledge of a 55 meter high building you throw a ball straight up with an initial speed of m/s. How long, to the nearest second, does it take to hit the ground?

 7

If the building in 6) was meters high and you throw the ball at 30 m/s, how high to the nearest meter does it go?

 8

A person jumps from a window meters high and is caught in a firefighter's net which stretches 0.6 meter. To the nearest tenth of a m/s^2, what is the magnitude of the person's acceleration in the net?

 9

How far to the nearest meter can a sprinter running at 9 m/s, travel in the time it takes a rock to fall meters?

 10

A helicopter travelling upward at m/s drops a package from a height of 500 meters. To the nearest second how long does it take to hit the ground?
