Question

(b) A racing car has a uniform acceleration of 8 m/s. What distance will it cover 12 s after the start?​

Answer 1

Answer:

Given:

Initial velocity is: u=0

Acceleration is: a=4 ms

2

Time is: t=10 s

Using second equation of motion:

s=ut+

=0+200=200 m

Answer 2

Answer:

Given:

Initial velocity is: u=0

Acceleration is: a=8 ms ^ 2

Time is: t=12 s

Using second equation of motion:

s=ut+ 1 / 2 at ^ 2

s=0×10+ 1 / 2 ×8 × 12 ^ 2

=0+576=576 m
