Explanation:
The Work done by any force is defined as the force applied times the displacement of point of application of force in the direction of force.
This is better represented as a scalar product of Force vector and displacement vector.
Here, the angle between force and displacement is .
∴ Magnitude of force =
Answer:
Explanation:
Force is equal to the product of mass and acceleration.
We know the mass, but not the acceleration. Therefore, we must calculate it before we can calculate force.
1. Calculate Acceleration
Acceleration is the change in velocity over the change in time.
The final velocity is 10 meters per second and the initial velocity is 4 meters per second. The time is 1 second.
Substitute the values into the formula.
Solve the numerator.
Divide.
2. Calculate Force
Now we know the acceleration and the mass.
Substitute the values into the fore formula.
Multiply.
- 1 kilogram meter per square second is equal to 1 Newton.
- Our answer of 12 kg*m/s² is equal to 12 Newtons
The force applies to the ball was <u>12 Newtons.</u>
