Answer: 9kgm/s
Explanation:
Given that,
Mass of ball = 3 kg
Speed by which ball moves = 3 m/s. Linear momentum of the ball = ?
Since momentum refers to the quantity of motion of the moving ball,
Linear momentum = Mass x Speed
= 3kg x 3m/s
= 9 kgm/s
Thus, the linear momentum of the ball is 9kgm/s
Possibly, what’s the question?
Answer:
53,130 J
Explanation:
When a certain substance absorbs heat, the temperature of the substance increases according to the equation:
where
Q is the amount of heat absorbed
m is the mass of the substance
C the specific heat capacity
the change in temperature of the substance
In this problem:
m = 2.3 kg is the mass of copper
is the increase in temperature
is the specific heat of copper
So, the amount of heat absorbed is:
