Which of the following is a measurement of acceleration?
100 miles per hour
9.8 m/s²
60 m/s
100 km/h
A student plans to bake a cake, so he rides his bike next door to borrow flour from his neighbor. On the way back, the sack of flour increases the overall mass of the student and his bike. How does this affect his acceleration as he rides his bike?
His acceleration increases.
His acceleration decreases.
There is no change to his acceleration.
His acceleration decreases then increases.
The student wants to be extra careful and does not apply as much force to the pedals to prevent the flour from falling. How does this affect his acceleration?
His acceleration increases.
His acceleration decreases.
There is no change to his acceleration.
His acceleration decreases then increases.
Two kickers on a football team are practicing kicking field goals. The first player kicks the ball with a force of 10 N. The second player kicks the ball with a force of 12 N. How would the increase in force by the second player change the acceleration of the football?
The increase in force would change the acceleration to 0 m/s².
The increase in force would decrease then increase the acceleration of the football.
The increase in force would decrease the acceleration of the football.
The increase in force would increase the acceleration of the football.
In Shop Class, a group of students are rebuilding a racing bike with their teacher. The engine is not large, and they have to use specific parts to make the car perform properly. They can choose parts with different masses. However, they need to remember that the goal of a racing bike is to be fast, so they want to choose parts that will help them achieve this goal.
The students must choose parts with a greater mass because objects with a greater mass will accelerate more quickly.
The students must choose parts that decrease the overall force of the bike because a decrease in force will increase the acceleration of the bike.
The students must choose parts with a smaller mass because objects with a smaller mass can accelerate more quickly.
The students must choose parts that maintain the same overall force of the bike because a constant force will change the acceleration of the bike.
Calculate the acceleration of the football for both kicks using the information in the diagram.
Kick 1: 0.041 m/s²; Kick 2: 0.034 m/s²
Kick 1: 4.1 m/s²; Kick 2: 4.92 m/s²
Kick 1: 24.39 m/s²; Kick 2: 29.27 m/s²
Kick 1: 27.90 m/s²; Kick 2: 29.30 m/s²
A mover is pushing a cart with a mass of 68 kg. She pushes with a force of 3 N. The mover places another box with a mass of 25 kg inside the cart. This increase in mass would ( increase / decrease ) the acceleration of the cart. She pushes the cart with more force to ( increase / decrease ) the cart’s acceleration. This makes mass ( directly / inversely ) proportional to acceleration and force ( directly / inversely ) proportional to acceleration.

8- Challenge! Rider 1 has a mass of 60 kg and rider 2 has a mass of 80 kg. The bike has a mass of 98 kg. Each rider takes a turn riding the bike. Rider 1 rides the bike with a forward force of 2100 N and rider 2 rides the bike with a forward force of 2190 N. What is the acceleration of the bike for each rider?
Rider 1: 0.040 m/s²; Rider 2: :0.036 m/s²
Rider 1: 13.29 m/s²; Rider 2: 12.30 m/s²
Rider 1: 21.32 m/s²; Rider 2: 22.34 m/s²
Rider 1: 35.00 m/s²; Rider 2: 27.36 m/s²
