Question

A warehouse employee is pushing a 30.0 kg desk across a floor at a constant speed of 0.50 m/s. What is the magnitude of the momentum of the desk?

a) 15 kg m/s
b) 30.0 kg m/s
c) 0.50 kg m/s
d) 60.0 kg m/s

Answer 1

The magnitude of the momentum of a 30.0 kg desk moving at 0.50 m/s is 15 kg m/s, calculated using the formula for momentum, p = mv.

Step-by-step explanation:

The question is asking to calculate the momentum of a desk that a warehouse employee is pushing across the floor. Momentum can be calculated using the equation p = mv, where p is momentum, m is mass, and v is velocity.

To calculate the momentum of the 30.0 kg desk moving at a constant speed of 0.50 m/s, you multiply the mass (m) by the velocity (v).

p = mv = 30.0 kg × 0.50 m/s = 15 kg m/s

Therefore, the magnitude of the momentum of the desk is 15 kg m/s, which corresponds to option a) of the provided choices.
