A student ran 60 meters in 1 minute. Calculate the speed. Provide your answer in meters per second.
1 answer:
Answer:
Speed, S = 0.5m/s
Explanation:
Given the following data;
Distance = 30 meters
Time = 1 minute = 60 seconds
To find the speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
Substituting into the above formula;
Speed, S = 0.5m/s

Explanation:
This figure given is the frequency; 2 times per second represents frequency.
What is frequency?
- It is the number of times per seconds something goes past or around another.
it is expressed as:
Frequency =
where n is the number of turns
t is the time taken
Therefore, the Barber spinned him 2 times in 1 second.
The period is the inverse of frequency. It is the time taken for a body to go through a point;
Period = =
