When the velocity of a body increases from 10 m/s to 15 m/s in 4 seconds, then the acceleration will be _____?
Answer: 1.25m/s²
Explanation
To find acceleration, we use the formula:
a = (v - u) / t
where:
v = final velocity = 15 m/s
u = initial velocity = 10 m/s
t = time = 4 seconds
a = (15 - 10) / 4
= 5 / 4
= 1.25 m/s²
