Question

Q7. Motorbike running at 25 metre per second is slowed down to 5 metre
per second in 2.5
seconds. Calculate :
1)acceleration
2) distance covered in the time it slows down.​

Answer 1

Answer:

1. 8m/s²

2. 12.5m

Explanation:

1. Here,

u=25m/s

v=5m/s

t=2.5s

now, a=v-u/t

=5-25/2.5

=-20/2.5

=8m/s²

2. Here,

v=5m/s

t=2.5s

Distance= s*t

=5*2.5

=12.5m
