An 8kg bowling ball is rolling in a straight line toward you. If its momentum is 16kg m/sec, how fast is it traveling?
I = momentum = m V = 8 V = 16
so V = 2 m/s
how fast must a 2500 kg bus move to have a momentum of 75000 kg m/sec?
To find the velocity or speed at which the bowling ball is traveling, we can use the equation:
momentum = mass * velocity
Given that the momentum of the bowling ball is 16 kg m/s and the mass of the bowling ball is 8 kg, we can rearrange the equation to solve for velocity:
velocity = momentum / mass
Plugging in the given values, we have:
velocity = 16 kg m/s / 8 kg
Simplifying the equation, we get:
velocity = 2 m/s
Therefore, the bowling ball is traveling at a speed of 2 meters per second.
To find the speed at which the 8kg bowling ball is traveling, we need to use the formula for momentum. Momentum is defined as the product of mass and velocity.
Momentum (p) = mass (m) × velocity (v)
We know the bowling ball's momentum is 16 kg m/sec and its mass is 8 kg. So we can rearrange the formula to solve for velocity:
v = p / m
Substituting the given values, we have:
v = 16 kg m/sec / 8 kg
Simplifying further, we get:
v = 2 m/sec
Therefore, the bowling ball is traveling at a speed of 2 meters per second.
