Williams kick ball with a force of 20Newton for a period of 0.03 second if the mass of the ball is 0.01 kg calculate the speed of the ball the speed of the ball kick by William
To calculate the speed of the ball kicked by William, we can use the formula:
Speed = Force / (Mass * Time)
Given:
Force = 20 Newton
Mass = 0.01 kg
Time = 0.03 second
Let's substitute the given values into the formula:
Speed = 20 N / (0.01 kg * 0.03 s)
First, let's calculate the denominator (Mass * Time):
Denominator = 0.01 kg * 0.03 s
Denominator = 0.0003 kg·s
Now, let's divide the force by the denominator to get the speed:
Speed = 20 N / 0.0003 kg·s
To simplify the units, we can convert kg·s to N·s by multiplying by 1000 (since 1 kg·s = 1000 N·s):
Speed = 20 N / (0.0003 kg·s * 1000)
Speed = 20 N / 0.3 N·s
Finally, let's divide the force by the denominator:
Speed = 66.67 m/s
Therefore, the speed of the ball kicked by William is 66.67 m/s.
