Moving in Space and Time1. A modern sports car can accelerate from a standing start to 62 mph (miles per hour) in 3.7 seconds.aConvert 62 mph to ms-1 (1 mile = 1609 m)

[1]bCalculate the acceleration of the car.

[1]

cHow far will the car travel as it accelerates from 0 to 62 mph?

[2]

dThe car can be brought to a stop from 62 mph in a distance of 50 m (the braking distance). Calculate the deceleration.

2. Throwing the hammer is an Olympic sport where the thrower whirls a tungsten ball around on the end of a metal chain, before releasing it.

aThe thrower releases the hammer at a velocity of 26 ms-1, at an angle of 40o to the horizontal. Calculate the horizontal and vertical components of the velocity.

Horizontal component

[2]

Vertical component

[2]bFind the maximum height above the release point reached by the hammer

[2]cFind the range, that is the horizontal distance travelled by the hammer.

[2]dSuggest why the actual range may be different to the value you have just calculated.
