Answer:
ø = 53.7º
Explanation:
The measurement of kinetic energy in an object is calculated based on the object's mass and velocity.
KE=1/2mv²
where m is mass
v is velocity
given data
m=0.60 kg
v=4.0 m/s
So
KE = 1/2 . 0.6 . 4^2
KE= 4.8 J
All the KE is converted into GPE ("Gravitational potential energy (GPE) - energy stored in an object when moving the object to a height")
4.8 = 0.6 . 9.8 . ∆h
∆h = 0.816 m
This is the height that the object rises.
cos ø = (2 – 0.816 ) / 2 = 0.592
ø = 53.7º
Accelerating pretty sure but be sure to double check the answer
Atoms of the same element having equal numbers of protons, but different numbers of neutrons is called isotope.
Something that goes round in circles could have a high speed but zero average velocity.
