A car starts from rest and accelerates uniformly at a rate of 2 metres per second square. The velocity of the car and distance covered at the end of 8 seconds is
12m/s, 32m
8m/s, 16m
16m/s, 64m
32m/s, 128m

Answer 1

distance covered by car in t seconds=0∗t+

2

1

at

2

for t=1 distance is 2m.

2=

2

1

a∗1

2

a=4m/s

2

velocity after 2 seconds.

v=u+at

=0+4∗2=8m/s

correct answer is option b
