According to the data given in the question,
A car traveling at 60mph applies its brakes and stops in 5 seconds. What is its...
The driver of a car traveling at 54 ft/sec suddenly applies the brakes. The position of the car is s=54t-31, 1 seconds after the driver applies the brakes. How many seconds after the driver applies the brakes does the car come to a stop? O A. 54 sec OB. 9 sec O C. 27 sec OD. 18 sec
P2.4-4) A car initially traveling at 60 mph coasts for 5 seconds. Due to friction and wind resistance, the car decelerates while coasting at a rate of 1 ft/s2. After the 5 seconds of coasting, the driver applies the brakes and decelerates at a constant rate eventually bringing the car to a stop. If the total time that the car travels is 8 seconds, determine the car's braking acceleration. Given: Find: Solution: Draw the acceleration and velocity curves. v (ft/s)...
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
Problem 3. A car is traveling at a speed of 20 m/s when the driver applies the brakes. The car stops in 5 seconds. How far (in meters) does the car travel in that time? Assume the car's deceleration is constant.
A test car accelerates from 0 to 60mph in 4.9 seconds. what is the average acceleration in stadard SI units. Assume1609 meters in one mile.
A car moving at 48 m/s brakes to a stop in 6 seconds. What is its acceleration?
A train which is traveling at 73 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 56 mi/hr as it passes a point 1/2 mi beyond A. A car moving at 36 mi/hr passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, t the driver "steps on the gas." Calculate the...

The driver of a car traveling on the highway suddenly slams on the brakes because of a slowdown in traffic ahead. A) If the car’s speed decreases at a constant rate from 74 mi/h to 50 mi/h in 3.0 s, what is the magnitude of its acceleration, assuming that it continues to move in a straight line? Answer is in mi/h^2 B) What distance does the car travel during the braking period? Answer is in ft
A car of mass 875 kg is traveling 30.0 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.60 s in the positive -direction before coming to rest. (a) What is the car's acceleration? (b) What magnitude force acted on the car during this time? (c) How far did the car travel? [Ans: ()-536 m/s (b) 4690 N(c) 84,0 m]
