Answer:
The catcher does negative work on the ball because the force exerted by the catcher is opposite in direction to the motion of the ball.
Explanation:
For the answer to the question above, asking what is the resistance force if a man weighing 700 N lifts a 50.0 N object 2.0 m high. He uses a lever and with a force of 10.0 N.
we can use the formula below for calculating lever
<span>thus, Le / Lr = 50 / 10 = 5 </span>
Answer:
Tension: No, Force of Gravity and Air Resistance: Yes.
Explanation:
The air resistance and the correspondent component of the force of gravity will do work since both they are parallel/antiparallel to the direction of motion. Tension will not do work, since its perpendicular to the direction of motion.
