Question

a curling stone is at rest on the ice. isabella pushes the curling stone with a force of 30 newtons to the right. the force of friction between the curling stone and the ice is 3 newtons the curling stone weighs 180 newtons.

complete the sentence.
when isabella pushes the curling stone, the magnitude of the stones velocity _______.

increases decreases does not change

Explanation:

Step1: Calculate net horizontal force

$F_{net} = F_{push} - F_{friction} = 30\ \text{N} - 3\ \text{N} = 27\ \text{N}$

Step2: Relate net force to motion

A positive net force (to the right) acts on the initially stationary stone, causing acceleration in the direction of the force. Acceleration means the magnitude of velocity (speed) increases over time.

Answer:

increases
