Question

what is the average speed of a cheetah that sprints 100m in 4 sec ? what if it sprint 50m in w sec​

Answer 1

Answer:

The average speed of cheetah is 25m/sec

Explanation:

Aveg. speed= total distance/total time

=100/4

=25m/sec.

Answer 2

Concept:

• One dimensional motion
• Speed is the distance covered per unit of time
• Speed, which is a scalar quantity, is the "speed at which an object is moving."
• The rate at which an object travels a distance can be thought of as its speed.
• A fast-moving object travels at a high speed and completes a significant distance in a brief period of time.

Given:

• Distance sprinted by the cheetah d = 100 m
• The time taken by the cheetah to sprint 100 m t = 4s

Find:

• The average speed of the cheetah.

Solution:

We know that speed is the distance covered per unit of time.

s = d/t

s = 100 m/ 4s = 25 m/s

If the cheetah sprints 50 m in w seconds, its speed is (50/w) m/s

The average speed of the cheetah is 25 m/s.
