Answer:
Explanation:
A machine is which no part of the work done on the machine is wasted, is called an ideal or perfect machine
Answer:
The answer is 80 kN . m (clockwise)
Explanation:
As,
M = P x L
Here, the towline exerts a force is P.
Substituting P for 4000N.
M = -4000N x 20m
= -80000N.m
= 80kN.m
Maximum moment about the point O is 80kN.m (Clockwise)
(150 meters) / (18 seconds) = 8.33 meters per second
The projectile maintains its horizontal component of speed because there's nothing exerting any horizontal force on it. <em>(b) </em>
Gravity has no effect on horizontal motion.
