How much force was applied to stop a bus traveling at 15.2 m/sec?
What was the force applied to the bus to stop it?
A bus is traveling down the road at 15.2 m/sec. In 8.25 seconds, the bus, which has a mass of 2480 kg, comes to a complete stop.
What was the force applied to the bus to stop it?
A) 3,758.8 N B) 4,096 N C) 5,556 N D) 6,180 N
Final answer:To stop the bus in 8.25 seconds, a force of approximately 4,096 Newtons was applied.
Force applied to stop the bus
To stop the bus in 8.25 seconds, a force of approximately 4,096 Newtons was applied. This force was determined by considering the mass of the bus, which is 2,480 kilograms, and the time it took for the bus to come to a complete stop.
Explanation:
To bring the bus to a stop, a force of approximately 4,096 Newtons was applied. This force was determined by considering the mass of the bus, which is 2,480 kilograms, and the time it took for the bus to come to a complete stop, which was 8.25 seconds. The negative sign in the force value indicates that the force acted in the opposite direction of the bus's initial motion.
Newton's second law, which relates force, mass, and acceleration, was utilized for this calculation. The negative acceleration of approximately 1.84 meters per second squared was derived from the change in velocity during the stopping period. The result, 4,096 Newtons, signifies the magnitude of the force required to decelerate and halt the moving bus.
