n Question 2 A crate sits on the back of a flatbed truck that is initially at rest. The truck driver steps on the gas, and the truck accelerates forward at a rate so high that the crate ends up slipping backward off the truck. What is the direction of the friction force acting on the crate, and the direction of the acceleration vector for the crate, as seen by the driver, looking in his rear-view mirror? According to the driver, is Newton's 2nd Law satisfied? □ The crate experiences a friction force toward the front of the truck, and has an acceleration directed backwards off the truck. The crate experiences a friction force toward the back of the truck, and has an acceleration directed toward the front of the truck. Newton's 2nd Law is NOT satisfied, according to the driver. O The crate experiences a friction force toward the back of the truck, and has an acceleration directed backwards off the truck. Newton's 2nd law is satisfied, according to the driver. □ The crate experiences a friction force toward the front of the truck, and has an acceleration directed toward the front of the truck. Question 3 A crate sits on the back of a flatbed truck that is initially at rest. The truck driver steps on the gas, and the truck accelerates forward at a rate so high that the crate ends up slipping backward off the truck. What is the direction of the friction force acting on the crate, and the direction of the acceleration vector of the crate, as seen by an observer standing by the side of the road? According to the bystander, is Newton's 2nd Law satisfied? The crate experiences a friction force toward the back of the truck, and has an acceleration directed toward the front of the truck. □ Newton's 2nd Law is NOT satisfied, according to the driver.
