A 1000kg car with a velocity of 25m/s brakes to a stop. how many calories of...
You are driving a car with speed of 100 miles per hour, you applied the brakes to avoid hitting a deer. How many calories of heat are produced in the stopping process if the car mass is 1000kg?
A 2500 kg car is traveling 25 m/s and brakes to a stop. This causes the brakes to heat up as the car’s kinetic energy is converted to thermal energy. If the heat in the brakes could be captured and applied to ice at 0 degrees Celsius, how much could it melt?
A bicycle and rider have a combined mass of 114.0 kg. How many calories of heat are generated in the brakes when the bicycle comes to a stop from a speed of 32.2 km/h? kcal
While a 1000kg car was traveling 50m/s, the brakes are applied to slow it down to 10m/s, what is the total work done on the car. A) 120,000 J B) 1200 kJ C) -120,000JD -1200 kJ E) None of the above vf I A constant force F is applied for 6 seconds to change the particle's velocity from vi to vy. Determine the force F if the particle's mass is 6 kg. A) (17.3 j) N C) (-17.3 j) N...
A 1,210 kg car going 32 m/s is brought to a stop using its brakes. Let's assume that a total of approximately 28 kg of iron in the brakes and wheels absorbs the heat produced by the friction. (a)What was the car's original kinetic energy (in J)? ________J (b)After the car has stopped, what is the change in temperature (in °C) of the brakes and wheels? ________ °C
9. A car moving initially with a speed of S m/s brakes to a stop in 10 s. The average braking force is 700 N. Find mass of the car.
an 1000kg car traveling at 80 m/s takes 19m to stop under full breaking. the same car under similar road conditions, traveling at 160m/s, takes ___________ m to stop under full breaking.
11. A driver traveling at 27.8m/s tries to stop the car and finds that the brakes have failed. The emergency brake is then pulled and the car comes to a stop in 130 m. Find the car's deceleration.
1. Calculate the impulse required to stop a 1000kg car moving north at 20 m s . In which direction would the impulse need to be delivered? answer
Question 181 A car moving at 20 m/s brakes and slides to a stop. If the coefficient of kinetic friction between the pavement and the tires of the car is 0.1, how far does the car slide? O A. 50 m O B. 100 m O C. 200 m O D. 400 m
