Question

A cell phone is at rest on a tabletop and the phone’s owner flicks the phone with their fingers, which applies a 0.01 N force to the phone. The phone is accelerated at a rate of 0.1 m/s2 in the direction of the flick. What is the mass of the phone?

Answer 1

• Force=0.01N=F
• Acceleration=a=0.1m/s^2
• Mass=m

$\\ \sf\longmapsto F=ma$

$\\ \sf\longmapsto m=\dfrac{F}{a}$

$\\ \sf\longmapsto m=\dfrac{0.01}{0.1}$

$\\ \sf\longmapsto m=0.1kg$

• m=100g
