1. Susan pushes her dad, David, on an ice rink with a force of 30 N. She weighs 45 kg and her dad weighs 100 kg. What are the ac

mamaluj [8]

Explanation:

Given parameters:

Force = 30N

Weight Susan = 45kg

Weight of Dad = 100kg

Unknown:

Acceleration of Susan = ?

Acceleration of Dad = ?

Solution:

Force = mass x acceleration

Acceleration = $\frac{force}{mass}$

Acceleration of Susan = $\frac{30}{45}$ = 0.67m/s²

Acceleration of Dad = $\frac{30}{100}$ = 0.3m/s²
