Question

A ball rolls 50 meters in
10 seconds *

A. 2 meters per second

B. 5 meters per second

C. 10 meters per second
D. 25 meters per second​

Answer 1

The speed of the ball is B. 5 meters per second

Explanation:

For an object in uniform motion (= at constant velocity), the speed can be calculated using the equation

$v=\frac{d}{t}$

where

v is the speed

d is the distance covered

t is the time taken

For the ball in this problem:

d = 50 m is the distance covered

t = 10 s is the time taken

Substituting, we find the speed:

$v=\frac{50}{10}=5 m/s$
