Okay. There is a simple formula to go with this where:
p = mv
P: Momentum.
M: Mass.
V: Velocity
Sub the numbers in and solve for M.
10.0 = m(1.5)
10.0/1.5 = m
6.67 kg = m
Therefore the mass of the ball is 6.67kg.
Its accelarating from 1-10 i know that because the line is going up. i hope i helped
Kinetic energy is energy of motion while temperature is a measure of that energy in substances.
