Question

a) An object is moving with a velocity of 5 m/s. Its velocity changes to 13 m/s in a
seconds. Calculate its acceleration
b) A scooter is travelling at 12m/s. if its accelerating at 3m/s^2 ,whats its velocity after 10 seconds?​

Answer 1

$\:\: \underline{\underline{\bf{\large\mathfrak{~~Solution~1~}}}}$

acceleration=(13-5)/1=8m/s²

$\:\: \underline{\underline{\bf{\large\mathfrak{~~Solution~2~}}}}$

velocity=12+3(10)=42m/sec

Answer 2

Explanation:

acceleration=(13-5)/1=8m/s²

velocity=12+3(10)=42m/sec
