Answer:4.22 J
Explanation:
Given
mass of pitcher 
Force applied 
distance moved 
Applying work-Energy theorem which states that work done by all the forces is equal to the change in kinetic energy of the object
Work done by force 
W=
change in kinetic Energy =
K.E.-0=
K.E.=
A real question, one with a question mark?
Latitude, elevation, ocean currents, topography, and prevailing winds. There's probably a few others but these are the most important.
The angle between 2 o'clock and 12 o'clock is referred to as the angle of twist. The angle between the planes of maximum shear which is bisected by the axis of greatest compression is angle of shear.
A :-) for this question , we should apply
F = ma
( i ) Given - m = 2 kg
a = 15 m/s^2
Solution :
F = ma
F = 2 x 15
F = 30 N
( ii ) Given - m = 2 kg
a = 10 m/s^2
Solution :
F = ma
F = 2 x 10
F = 20 N
.:. The net force of object ( i ) has greater force compared to object ( ii ) by
( 30 - 20 ) 10 N
