a 2.0-kg ball has a momentum of 25 kg*m/s. what is the ball's speed?
50
p = m*v
25/2 = g\v
To find the ball's speed, we can use the formula:
Momentum (p) = mass (m) * velocity (v)
Given that momentum (p) = 25 kg*m/s and mass (m) = 2.0 kg, we can rearrange the formula to solve for velocity (v):
v = p / m
Plugging in the values, we have:
v = 25 kg*m/s / 2.0 kg
v = 12.5 m/s
Therefore, the ball's speed is 12.5 m/s.
To find the ball's speed, we can use the formula for momentum:
Momentum = mass × velocity
Given that the ball's momentum is 25 kg*m/s and its mass is 2.0 kg, we can rearrange the formula to solve for velocity:
velocity = Momentum / mass
Substituting the given values, we have:
velocity = 25 kg*m/s / 2.0 kg
velocity = 12.5 m/s
Therefore, the ball's speed is 12.5 m/s.
