Physics! Please help 3. A sled cruising down the lane at 22 m/s applies the brakes...
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 car of mass 772 kg is traveling 24.4 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.27 s in the positive x-direction before coming to rest. a). What is the car's acceleration (in m/s2)? (Indicate the direction with the sign of your answer.) b). What magnitude force (in N) acted on the car during this time? c). How far (in m) did the car travel?
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)...
An electric vehicle starts from rest and accelerates at a rate of 2.2 m/s2 in a straight line until it reaches a speed of 22 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops.(a) How much time elapses from start to stop (in seconds)?(b) How far does the vehicle travel from start to stop (in meters)?
A train is traveling down a straight track at 33 m/s when the engineer applies the brakes, resulting in an acceleration of -1.0 m/s2 as long as the train is in motion. How far does the train move during a 66-s time interval starting at the instant the brakes are applied? Enter a number swer is not zero. m Need Help? Read

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.
Answer all and write clearly please A driver, cruising along at 55 mph, sees the traffic light turn red. He steps on the brakes and decelerates at a constant 5.0 m/s2. 4. 55 mph (a) What is the speed of the car in m/s? (10 points) (b) How far did he travel before coming to rest? (10 points) (c) How long does it take him to come to a stop? (10 points)
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]
A car slows down uniformly from a speed of 28.0 m/s to rest in 9.00 s How far did it travel in that time?
