seconds. What is the magnitude of the acceleration in m/s
2
to 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 persons acceleration (assumed to be constant) 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?

m/s drops a package from a height of 500 meters, to the nearest second how long does it take to hit the ground?
