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 determine the vertical force exerted at the blocks by the sprinter, we need to find the component of the 850N force that acts in the vertical direction.
First, we can find the vertical component of the force by using trigonometry. The vertical component is given by the formula:
Vertical component = Force * sin(angle)
where the force is 850N, and the angle is 25 degrees.
Plugging in the values, we get:
Vertical component = 850N * sin(25 degrees)
To find the answer, you can calculate the sine of 25 degrees (approximately 0.423), and multiply it by 850N:
Vertical component = 850N * 0.423
The vertical force exerted at the blocks is approximately 359.55N.
