Tom swatted Beth's jump shot 25 m into the stands with a force of 100 N. How much work did he do?
a) 2500 J
b) 4 J
c) 125 J
d)75 J
ok so like theres this rlly helpful calculator on calculator soup that says the answer is 2500 j. idk if its rlly right but i think so, so im also using this answer
Also, how would you find the answer? what formula would u use?
I have no idea. Is that all the information you are given?
Work in = force* distance moved in direction of the force
It is also equal to the gain of kinetic energy of the ball. but I have no idea if the 25 meters is upward or what the mass is.
To calculate the work done, we can use the formula:
Work = Force * Distance * cos(theta)
where:
- Force represents the amount of force applied (in newtons)
- Distance represents the distance over which the force is applied (in meters)
- theta represents the angle between the applied force and the direction of the displacement (usually 0 degrees if the force is applied along the same line as the displacement)
In this case, the distance is given as 25 m and the force is given as 100 N. Since the force is acting in the same direction as the displacement (assuming it is not at an angle), the angle theta is 0 degrees.
Using the formula, we have:
Work = 100 N * 25 m * cos(0 degrees)
cos(0 degrees) equals 1, so the equation simplifies to:
Work = 100 N * 25 m * 1
Work = 2500 J
Therefore, the correct answer is option a) 2500 J.
