Please help!

Marcy uses a marble launcher to accelerate a 10g marble at a rate of 10 m/s^2. Calculate the size of the force needed tolaunch the marble at a rate of 30 m/s^2. (10g = 0.01kg)

Answer 1

Answer: 0.3 N

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* 30=0.3\ N`

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