a sprinter exerts 850N on the starting blocks at 25 degrees to the horizon at the beginning of a race. what is the vertical force exerted at the blocks?
To find the vertical force exerted at the start blocks by the sprinter, we need to find the vertical component of the 850N force at an angle of 25 degrees to the horizon. This can be accomplished using trigonometry.
The vertical component, also known as the force in the y-direction, can be calculated using the formula:
Vertical Force = Force * sin(angle)
In this case, the force is 850N and the angle is 25 degrees.
Vertical Force = 850N * sin(25 degrees)
Now, let's evaluate this equation:
sin(25 degrees) ≈ 0.423
Vertical Force = 850N * 0.423
Vertical Force ≈ 359.55N
Therefore, the vertical force exerted at the starting blocks by the sprinter is approximately 359.55N.
