how much work can a 50.0kg wreckin ball traveling at 5.00m/s do when striking a building
How much Kinetic energy does it have when moving at that speed?
To determine the amount of work done by a wrecking ball when striking a building, we need to use the formula for work:
Work = Force × Distance × cosine(theta)
However, we need to calculate the force first. The force exerted by the wrecking ball is determined by its mass and velocity, using the formula:
Force = mass × acceleration
In this case, the acceleration is caused by the object coming to a halt when it strikes the building. So, we will use the formula for deceleration:
deceleration = (final velocity - initial velocity) / time
Given that the wrecking ball comes to a halt, the final velocity is 0 m/s. We also need to find the time it takes for the ball to stop. To do that, we require additional information about the building, such as its elasticity or the distance over which the wrecking ball stops.
Without this information, we cannot determine the exact amount of work done by the wrecking ball.
