Question

An object moves along
straight line with an acceleration of 2 m/s² . if its initial speed is 10m/s, what will be its speed 5sec later?​

Answer 1

Answer:

first equation of motion will be applied

v=u+at

Explanation:

a=2m/s

u=10m/s

t=5sec

v=u+at

=10+2*5

=10+10

=20m/s is the final velocity

Answer 2

Answer:

u = 10m/s , a = 2m/s and time = 5sec

v = u + at

v = 10 + 2*5

v = 10 + 10

v = 20m/s

so the speed is 20m/s
