Compute for the total mechanical energy of a 3.5 kg baseball dropped from a height of 3 meters moving at a speed of 10 m/s.

277.9 J

Explanation:

We are given that

Mass,m=3.5 kg

Height=3 m

Speed,v=10 m/s

Kinetic energy of baseball=

Potential energy of baseball=P.E=mgh

g=

Substitute the values

Potential energy of baseball=

Total mechanical energy=K.E+P.E

Total mechanical energy=175+102.9=277.9 J

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
