Energy is force * distance.
So force is energy/distance so 6000J/300m = 20N
<span>The weight lifted by a machine to the applied force on a machine is called mechanical advantage.
This is written as Mechanical advantage, M. A, = load(weight)/effort.
So for 1) M.A = 2 and load = 2, 000lb = 8896.446N.
So 2 = 8896.446/ effort
Effort = 8896.446/2 = 4448.48
Similarly for M.A of 2, 000, 000 we have
Effort = 8896.446/ 2, 000, 000 = 0.004448</span>
Answer:
0.34 s
Explanation:
Given that,
Initial speed of a ball, u = 5.8 m/s
It is kicked at an angle of 17.0° above the horizontal.
The vertical component of velocity will be,

Let it takes t time in the air before it lands on the ground again. It can calculated as :

So, it will take 0.34 seconds.
