Question

A 15 kg bag is sitting on an elevator that is moving upwards at a constant velocity of 4m/s, jimmy k (77 kg) is standing next to it (also in the elevator). What is the normal force acting on the bag

Answer 1

The normal force acting on the bag can be calculated using the mass of the bag and the person standing next to it.

Step-by-step explanation:

The normal force is the force exerted by a surface to support the weight of an object resting on it. In this case, the normal force acting on the bag can be calculated using the equation:

Fnormal = mbag * g + mJimmy * g

where mbag is the mass of the bag, mJimmy is the mass of Jimmy, and g is the acceleration due to gravity (9.8 m/s²). Plugging in the values, we get:

Fnormal = (15 kg) * (9.8 m/s²) + (77 kg) * (9.8 m/s²)

Fnormal = 147 N + 754.6 N = 901.6 N

Therefore, the normal force acting on the bag is 901.6 N.
