Find the acceleration?

Answer 1

✯Question✯

• The velocity of an object increases at a constant from 20m/s to 50m/s in 10s.  Find the acceleration.

✬Solution✬

• u = 20m/s ( Initial velocity )
• v = 50m/s ( final velocity )
• t = 10s ( time taken )
• a = v - u ÷ t ( acceleration )
• a = 50 - 20 ÷ 10
• a = ³⁰⁄₁₀
• a = 3m/s

✵Acceleration of the object = 3m/s✵
