Answer:
the 3 one
Explanation:because the other one dont make since
<span>This is best understood with Newtons Third Law of Motion: for every action there is an equal and opposite reaction. That should allow you to see the answer.</span>
The formula for finding potential energy is: f= m*g*h. where "m" is mass of the object in question. "g" is the gravitational acceleration."h" is height above the ground. So, if we put in the values:
joules
Answer:
No, the ball will not clear the fence.
Solution:
Angular velocity,
Height, h = 1.2 m
Angle,
Distance covered by the ball, d = 110 m
Length of the fence, l = 1.2 m
Radius of the axis, R = 46 cm = 0.46 m
Now,
To calculate the linear velocity of the ball, v:
Total time taken:
The distance at which the ball falls, with a = 0 is given by:
Since, the ball has to clear a fence 1.2 m long and a t a distance 110 m away, clearly it will not be able to cross it.
