Given: m = 0.25kg
∑F = +3N
Note: Net force(∑F) is positive because the ball rolls to the right.
Note: Mass(m) is converted to kilograms(kg), since kilograms(kg) is the standard unit for mass.
g → kg
250g × 1kg / 1000g = 0.25kg
Unknown: a = ?
Formula: a = ∑F/m
Note: Formula was derived from the original formula of net force which is, ∑F = ma.
• ∑F = ma ← divide both sides by m
• ∑F/m = ma/m ← cancel like terms
• ∑F/m = a ← formula to find acceleration
Solution:
a = ∑F/m
= 3N / 0.25kg
= 12m/s²
Final Answer: a = 12m/s²
Note: If conversion of mass did not happen from your previous lessons, just change it back to 250g then solve. The answer must be 0.012m/s²
Reminder: Don't forget the units.
