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: v=8,7m/s
Explanation:
Quando dois corpos andam aglutinados, significam que têm a mesma velocidade, e a quantidade de movimento antes de uma colisão, é igual á quantidade de tempo depois dessa colisão
Answer:
V = 38.582 m/s
Explanation:
Initial Vertical Velocity = 0
Let's use the motion equation given below to solve for the final vertical velocity:
Here a = 9.81 m/s^2
and s = 30 m
Solving for v, we get:
v = 24.261 m/s
This is just the vertical velocity, to get the total velocity we need to add the horizontal component of velocity with this:
Total velocity = Sqrt ( Horizontal Velocity^2 + Vertical Velocity^2)
where and
V = 38.582 m/s
