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.
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
A car is moving at a speed of 60 m/s, when the driver applies the brakes, which causes a deceleration of 2 m/s2. How many seconds will it take for the car to stop and how far will it travel till it stops? 30 sec, 450 meters 25 sec, 800 meters 30 sec, 1800 meters 20 sec, 900 meters 30 sec, 900 meters
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
1. A sports car moving at a constant velocity travels 120 m in 5.0 s. If it then brakes and comes to a stop in 4.0 s, what is the magnitude of its acceleration (assumed constant) in m/s^2 and in g's (g=9.80 m/s^2). 2. A car slows down from 28 m/s to rest in a distance of 88 m. What was its acceleration, assumed constant?
A car traveling at 60mph applies its brakes and stops in 5 seconds. What is its acceleration [ft/sec^2]?
A sports car moving at constant velocity travels 110 m in 5.1 s . If it then brakes and comes to a stop in 4.5 s , what is the magnitude of its acceleration (assumed constant) in m/s2? Express the answer in terms of "g's," where g=9.80m/s2.
The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.65 s to a final velocity of 1.95 m/s, at which point the brakes are released (a) What was its initial speed (in m/s), just before the brakes were applied?(b) What was its acceleration (in m / s²) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the...
2.10 A car is going 35 m/s when the driver applies the brakes. a) If the braking acceleration is −5.7 m/s2 , how far will the car go as its velocity drops from 35 m/s to 22 m/s? b) How much time will the change from 35 m/s to 22 m/s take? 2.11 As hockey puck slides to a stop, it goes 40 m across the ice in 3.7 s. a) What was the initial velocity of the puck? b)...
A sports car moving at constant velocity travels 110 m in 5.0 s . 1.)If it then brakes and comes to a stop in 4.3 s , what is the magnitude of its acceleration (assumed constant) in m/s2? 2.)Express the answer in terms of "g's," where g=9.80m/s2. Express your answer using two significant figures.
