Answer: 0.3 N
Step-by-step explanation:
Given
Mass of marble is [tex]m=10g\ \text{or}\ 0.01\ kg[/tex]
Required acceleration [tex]a=30\ m/s^2[/tex]
Force is given as the product of mass and acceleration
[tex]F=ma[/tex]
Put the values
[tex]F=0.01\times 30=0.3\ N[/tex]
A force of [tex]0.3\ N[/tex] is required to launch the marble.
