Question

A deer starts from rest, and accelerates at 2 m/s2

for 10 seconds. Calculate :

(a) The final velocity

(b) The distance travelled.​

Answer 1

1. velocity = displacement / change the time

: d= v/t

d= 2m/s2/10 second

d=0.2m/s2

velocity = 0.2m/s2 / 10s

velocity = 0.02m/s2

2. distance = speed/time

d=s/t

first - last speed = 2+2 = 4 m/s2

time = 10+10 = 20s

d=s/t

d=4/20

d= 5m/s2
