<h3>
Answer:</h3>
24860 N
<h3>
Explanation:</h3>
From the question;
- Mechanical advantage is 0.0893
- Output force is 2220 Newtons
We are required to determine the input force;
- We know that mechanical advantage is the ratio of output force to input force.
- That is; M.A. = Output force ÷ Input force
- Rearranging the formula;
Input force = Output force ÷ M.A.
Therefore;
Input force = 2220 N ÷ 0.0893
= 24860 N
Hence, the input force is 24860 N
<span>You should deflect the
ball in order to maximize your speed on the skateboard.
Since this creates a larger impulse, you want to deflect the ball. Splitting it
up into catching and throwing the ball may by something you can think of deflecting
the ball. First, you need to catch the ball, which in turn would push you
forward with some speed. (The speed we are talking about should obviously be
equal to option A, where you catch the ball). Now, throw the ball back to him
since these two processes are equal to deflecting the ball. Throwing a mass away
from you would cause or enable you to move even fast.</span>
D is not a scientific experiment.
False, the object will stay still or continue moving at the same speed and in the same direction.
Answer:
power is the rate at which energy is transferred or converted
the unit of power is Watts
