1. You apply a force of 0.35 N [up] to lift a fork. The resulting acceleration of the
fork is 0.15 m/s2 [up]. Determine the mass of the fork in grams.
To find the mass of the fork, we can use the formula F = ma (Newton's second law), where F is the force applied, m is the mass of the object, and a is the acceleration.
Given:
Force (F) = 0.35 N [up]
Acceleration (a) = 0.15 m/s^2 [up]
Using the formula F = ma, we can rearrange it to solve for mass:
m = F / a
Plugging in the values:
m = 0.35 N / 0.15 m/s^2
m = 2.33 kg
To convert the mass to grams, we multiply by 1000:
2.33 kg * 1000 g/kg = 2330 grams
Therefore, the mass of the fork is 2330 grams.
