The mechanical advantage of the crowbar is
(output force) divided by (input force) .
According to the gripping scenario, that's (750N) / (50N) = <em>15</em> .
Yasher koach, Yosef !
The acceleration of the ball would be around 9.1666667m/s
To work this out use this formula
acceleration = distance*velocity/distance*time
Answer:
1.28 m
Explanation:
You are given the initial speed that is 5 m/s. Since the coin is sent upwards, this means that the speed is positive according to the co-ordinate system in the y axis. Additionally, there is the gravity that curbs the coin in the opposite direction making the final speed becomes zero at the highest point, so the gravity takes negative sign.
So, from the explanation we have:
so, we use the following equation to find y (hight)
