Question

1. which factor best explains why figure a is more difficult to push? a figure b has less mass, so it has more inertia. b there are more unbalanced forces on figure a. c there are more balanced forces on figure b. d figure a has more mass, so it has more inertia. 5) brad and erin decide to have a tug - of - war. erin pulls the rope with all her might(strength) and so does brad. sadly, brad only puts forth half the force that erin pulls with. which way will the rope move? a) towards erin since forces are unbalanced b) towards brad, since forces are balanced c) towards brad since forces are unbalanced d) towards erin, since forces are balanced 6.) maya wants to test how friction affects the speed of a motorcycle. which surface would most likely create the most friction? a) concrete c) snow b) glass d) grass

Explanation:

Step1: Analyze tug - of - war forces

Erin exerts a force $F_{E}$ and Brad exerts a force $F_{B}=\frac{1}{2}F_{E}$. Since $F_{E}>F_{B}$, the net force is in Erin's direction. Unbalanced forces cause motion in the direction of the net force.

Step2: Analyze friction on surfaces

Concrete has a rougher texture compared to glass, snow, and grass for a motorcycle. Rougher surfaces generally create more friction.

Answer:

1. A. Towards Erin since forces are unbalanced
2. A. concrete
