Understanding Newton's Second Law

Kevin is driving his car, which has a mass of 1,250 kg, on a highway. He's feeling adventurous and decides to accelerate at a rate of 2.4 m/s². Can you calculate the net force acting on Kevin's car as he zooms down the road?

• 3,000 N

• 3,750 N

• 4,000 N

Jerry and Emily are having a friendly race on their bicycles. Jerry decides to pedal harder, increasing the force he applies to his bicycle from 150 N to 300 N. If the combined mass of Jerry and his bicycle remains constant at 75 kg, what happens to the acceleration of his bicycle?

• It is halved

• It remains the same

• It doubles

• It quadruples

Emily is rushing through the airport with her 5.5 kg suitcase, trying to catch her flight. She's pushing it with a net force of 18.7 N. Can you help her figure out the acceleration of her suitcase?

• 2.4 m/s²

• 3.4 m/s²

• 3.8 m/s²

• 4.2 m/s²

Fernanda is driving a delivery truck with a mass of 12,500 kg, and she's having a blast accelerating at 2.8 m/s². Suddenly, Kevin decides to load the truck with extra party supplies, doubling its mass to 25,000 kg! If the net force remains constant, can you guess what the new acceleration will be as they zoom off to the party?

• 1.4 m/s²

• 2.0 m/s²

• 2.8 m/s²

• 3.6 m/s²

Dustin's drone, weighing 2.3 kg, is on a thrilling mission to dodge an unexpected obstacle! To make this daring escape, it needs to accelerate at 3.7 m/s². Can you calculate the net force required for Dustin's drone to pull off this exciting maneuver?

• 6.1 N

• 7.5 N

• 8.5 N

• 9.1 N

During a friendly basketball match, Landon throws a 3.2 kg basketball with a force of 16.8 N. Can you calculate the acceleration of the basketball to help Landon win the game?

• 4.5 m/s²

• 5.3 m/s²

• 5.8 m/s²

• 6.2 m/s²

Emma, the adventurous 50 kg skateboarder, is zooming down the street with an acceleration of 2.5 m/s². Suddenly, she decides to take a break and stops pushing, causing the net force to be reduced by half. What will be Emma's new acceleration as she glides along?

• 0.75 m/s²

• 1.25 m/s²

• 1.75 m/s²

• 2.5 m/s²

• 3.0 m/s²

• 3.5 m/s²

• 4.0 m/s²

• 4.5 m/s²

Keeli and Emily are having a sled race on a snowy hill. Keeli's sled, weighing 20 kg, is being pulled with a force that makes it accelerate at 4.5 m/s². Suddenly, Emily decides to increase the pulling force on Keeli's sled to 180 N. What is the new acceleration of Keeli's sled?

• 6.0 m/s²

• 7.5 m/s²

• 9.0 m/s²

• 10.5 m/s²
