Driving down the road, you hit the brakes suddenly. As a result, your body moves toward the front of the car. Explain, using Newton’s laws.

Expert Solution & Answer

To determine

The reason due to which the body of a person moves toward the front of the car when the brakes apply suddenly.

Answer to Problem 1CQ

The body of a person moves toward the front of the car when the brakes apply suddenly is due to the inertia of motion.

Explanation of Solution

Inertia is the property of any object to resist the change its state of motion or state.

The Newton’s first law of motion states that an object remains in its state of rest or motion until or unless a external force applied on it. This is also known as the law of inertia.

When the brakes of the car apply suddenly then the body of person wants to remain in the state of motion due to the inertia. Thus the person moves toward the front of the car.

Conclusion:

Therefore, the body of a person moves toward the front of the car when the brakes apply suddenly is due to the inertia of motion.

Sketch the resulting complex wave form, and then say whether it is a periodic or aperiodic wave.

During a concentric loading of the quadriceps muscle in the upper leg, an athlete extends his lower leg from a vertical position (see figure (a)) to a fully extended horizontal position (see figure (b)) at a constant angular speed of 45.0° per second. Two of the four quadriceps muscles, the vastis intermedius and the rectus femoris, terminate at the patellar tendon which is attached to the top of the tibia in the lower leg. The distance from the point of attachment of the patellar tendon to the rotation axis of the tibia relative to the femur is 4.10 cm in this athlete. a b (a) The two quadriceps muscles can exert a maximum force of 225 N through the patellar tendon. This force is applied at an angle of 25.0° to the section of the tibia between the attachment point and the rotation axis. What is the torque (in N⚫ m) exerted by the muscle on the lower leg during this motion? (Enter the magnitude.) N⚫ m (b) What is the power (in W) generated by the athlete during the motion? W (c)…
