The equation for force is F=ma. Because we have the value of mass (0.42 kg) and the acceleration (14.8 m/s^2), simply plug them into the equation for force to get

The answer is 6.22 N because newtons are the unit used to measure force.
Answer:
a) 0.022%
b) 10014.32 lb
Explanation:
a) Percentage uncertainty would be

Percent uncertainty is 0.022%
b) For 1 kg uncertainty mass in kg would be

Mass in pounds would be

Mass in pound-mass is 10014.32 lb
Answer:
P=2736 Pa
Explanation:
According to Newton we have that:
∑
A force is exerted by the elevator to the suitcase, according to 3th Newton's law an equal force but in the opposite direction will appeared on the suitcase, that is:
∑

We know that the pressure is given by:
