The force exerted by the seat belt is given by Newton's second law. According to which
This is the answer.

6. When a moving car is brought to a stop with its breaks, its acceleration vector is A. in the same direction as its velocity B. equal to zero C. directed downward D. directed upward E. opposite to the velocity vector 7. A 2 000-kg sailboat experiences an eastward force of 3 000 N by the ocean tide and a wind force against its sails with magnitude of 6 000 N directed toward the northwest (45° N of W). What...
A car moving at 8.0 m/s crashes into a tree and stops in 0.24 s. Calculate the force the seat belt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 75 kg
A car is moving at a relatively slow speed, let's say a good running speed for a short distance sprint, when it hits a solid wall (top figure). The car comes to a complete stop, with a somewhat shorter front section now. The driver, who was not wearing a seat belt, tries to hold himself off the steering wheel. Let us find the necessary average force acting on the 86-kg driver that is necessary to bring him to a complete...
In an emergency stop to avoid an accident, a shoulder strap seat belt holds a 51.5 kg passenger firmly in place. If the car were initially traveling at 85.0 km/h and came to a stop in 6.1 s along a straight, level road, what was the magnitude of the average force applied to the passenger by the seatbelt?
6. When a moving car is brought to a stop with its breaks, its accelermation vector is A. in the same direction as its velocity B. equal to zero C. directed downward D. directed upward E. opposite to the velocity vector 7. A 2 000-kg sailboat experiences an eastward force of 3 000 N by the ocean tide and a wind force against its sails with magnitude of 6 000 N directed toward the northwest (45P N of W What...
A 1300-kg car, initially at rest, is initially accelerated at 4.9m/s2. After the car moves 550m, the engine is cut off. The car then moves a distance of 1230 before coming to a stop. Assume the road to be level and that g = 10 N/kg. a) What is in m/s, the magnitude of the velocity of the car at the end of the first 550m? b) What is in m/s2, the magnitude of the acceleration of the car while...
Sam's job at the amusement park is to slow down and bring to a stop the boats in the log ride.If a boat and its riders have a mass of 800 kg and the boat drifts in at 1.5 m/s how much work does Sam do to stop it? (answer in J)
Sam's job at the amusement park is to slow down and bring to a stop the boats in the log ride. If a boat and its riders have a mass of 1200 kg and the boat drifts in at 1.4 m/s how much work does Sam do to stop it? W=___ J
During a very quick stop, a car decelerates at 7m/s2. What is the angular acceleration of its 0.28m radius tires, assuming they do not slip on the pavement?
1. A light car of mass 2kg hits a heavy car of mass 100kg at rest with a force of magnitude F. (i) If the acceleration of the heavy car (100 kg) is 0.2 m/s2 after impact, how much force (F) does the heavy car exert on the light car? (ii) What is the accelerations of the light car (2 kg)?
