To solve this problem it is necessary to apply the equations related to the conservation of momentum. Mathematically this can be expressed as
Where,
= Mass of each object
= Initial velocity of each object
= Final Velocity
Since the receiver's body is static for the initial velocity we have that the equation would become
Therefore the velocity right after catching the ball is 0.0975m/s
A person walks up a flight of stairs √
Wind lifts a balloon into the air √
A weightlifter holds a barbell straight overhead √
Gravity is used in most real world examples because if not of gravity everyone would be floating all around ^-^
Hope this helps ;p
I= V/R
R= V/I these are the other two quantities

Answer:It is not affected by the change in media.</h2>
Explanation:
Transverse waves are those waves where the medium particles vibrate perpendicular to the direction of propagation.
Transverse waves do not require any medium.
They travel with same speed in any medium.
Electromagnetic waves are transverse waves where the medium particles vibrate perpendicular to the direction of propagation.
So,their speed is same in any medium.
Answer:
work accomplished = 300*30
= 9,000 J
applied work = 9,000 + 2,000 = 11,000 Joules
efficiency = 100 * work accomplished/work applied
= (9/11)100 = 81.8 %
force applied = (300/6)/.818
= 61.1 N
assuming that the 6 in your question refers to mechanical advantage
