Question

a bicycle initially moving with a velocity 5.0m\s accelerates for 5s at a rate of 2m\s square.What will be the final velocity.

Answer 1

Initial velocity of the bicycle (u) = 5 m/s

Acceleration (a) = 2 m/s^2

Time (t) = 5 sec

Let the final velocity of the bicycle be v.

Now, using first equation of the motion:

$v = u +at$

$v = 5 + 2 \times 5$

v = 5 + 10

v = 15 m/s

Hence, the final velocity of the bicycle is 15 m/s

Answer 2

u=5m/s
a=5s
t=2m/s
v=u+at
v=5+5×2
v=15m/s
