Tension in the rope due to applied force will be given as
angle of applied force with horizontal is 37 degree
displacement along the floor = 6.1 m
so here we can use the formula of work done
now we can plug in all values above
So here work done to pull is given by 691.8 J
Answer:
The kinetic energy of the baseball is 306.25 joules.
Explanation:
SInce the baseball can be considered a particle, that is, that effects from geometry can be neglected, the kinetic energy (), in joules, is entirely translational, whose formula is:
(1)
Where:
- Mass, in kilograms.
- Speed, in meters per second.
If we know that and
, then the kinetic energy of the baseball thrown by the player is:
The kinetic energy of the baseball is 306.25 joules.
