A Newton is 1 kg * m / s^2.
The force here is 20 kg * 5m / s^2.
You should see it clearly from there.
the maximum force a grocery sack can with stand and not rip is 250 N. if 20 kg of groceries are lifted from the floor to the table with an acceleration of 5 m/s squared, will the sack hold?

Total force on the sack:
F = mass (total acceleration)
= mass (g + 5 m/s²) [not forgetting the weight]
= 20(9.8+5)
=20*14.8
= 296 N. >250 N
F = mass (total acceleration)
= mass (g + 5 m/s²) [not forgetting the weight]
= 20(9.8+5)
=20*14.8
= 296 N. >250 N
