Finding acceleration of an object given force and mass?

Click For Summary
SUMMARY

The acceleration of an object can be calculated using Newton's second law, F=ma. In this discussion, a snooker ball with a mass of 100g (converted to 0.1kg) is subjected to a force of 20N. The correct calculation for acceleration is a=F/m, resulting in an acceleration of 200 m/s² when using the mass in kilograms. The error in the initial calculation stemmed from incorrect mass conversion and unit application.

PREREQUISITES
  • Understanding of Newton's second law (F=ma)
  • Knowledge of unit conversion from grams to kilograms
  • Basic principles of force and acceleration
  • Familiarity with metric units of measurement
NEXT STEPS
  • Review unit conversion techniques for mass and force
  • Study detailed applications of Newton's laws in various contexts
  • Explore examples of calculating acceleration in different scenarios
  • Learn about the implications of force duration on acceleration
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding the principles of force and acceleration in practical applications.

Homework Statement


Snooker ball with mass 100g is struck by a billiard cue. Cue imparts a force of 20N to the ball and the duration of the impact is 0.01s.

Homework Equations


F=ma

The Attempt at a Solution


F=ma
20=1(a) *I converted 100g to 1kg*
a= 20ms(^-2)

The answers claim that the acceleration is 200ms^-2. Except, I do not know how they have come to this, and which conversions I got wrong. I also left 100g in grams, but still did not result in the given answer.

Thank you if you can help me :-)

To convert from grams to kilograms, you need to divide the mass in grams by 1000.
