Question

Calculate the speed of a horse if it starts from rest and accelerates at 1.5 m/s² over a distance of 100m. Help, please!

A) 10 m/s
B) 15 m/s
C) 20 m/s
D) 25 m/s

Answer 1

The speed of the horse is 15 m/s.

Step-by-step explanation:

To calculate the speed of the horse, we can use the equation:

final velocity = initial velocity + (acceleration imes time)

In this case, the horse starts from rest, so the initial velocity is 0 m/s. The acceleration is given as 1.5 m/s² and the distance covered is 100m. We can rearrange the equation to solve for the final velocity:

final velocity = initial velocity + (acceleration imes time)

final velocity = 0 + (1.5 imes time)

final velocity = 1.5 imes time

Substituting the value for time:

final velocity = 1.5 imes 10 s

Simplifying the equation, we find that the final velocity is 15 m/s. Therefore, the speed of the horse is 15 m/s.
