Question

if a body have intial velocity of 10.0 m/s and it attains a velocity of 20m/s in 5 seconds then its accerleration ?

Answer 1

Answer:

a=20m/s²

Explanation:

v=u+at

20=10+a*5

20-10=5a

10=5a

a=100/5

a=20m/s²

Answer 2

u = 10 m/s

v = 20 m/s

t = 5 s

a = ?

a = v - u / t

a = 20 - 10 / 5

a = 2 m/s²
