Question

A 0.02 N push accelerates a table-tennis ball along a table at 8 m/s2 north. What is the mass of the ball?

I need answers ASAP!

Answer 1

• Force=0.02N=F
• Acceleration=a=8m/s^2
• Mass=m

According to Newton's second law

`\\ \sf\longmapsto F=ma`

`\\ \sf\longmapsto m=(F)/(a)`

`\\ \sf\longmapsto m=(0.02)/(8)`

`\\ \sf\longmapsto m=0.0025kg`

`\\ \sf\longmapsto m=2.5g`
