Answer 1

Answer: 0.3 N

Step-by-step explanation:

Given

Mass of marble is $m=10g\ \text{or}\ 0.01\ kg$

Required acceleration $a=30\ m/s^2$

Force is given as the product of mass and acceleration

$F=ma$

Put the values

$F=0.01\times 30=0.3\ N$

A force of $0.3\ N$ is required to launch the marble.
