Problem 3. A car is traveling at a speed of 20 m/s when the driver applies...
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 is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...
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 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?
A driver is traveling at a speed of 70 km/h in car A when he looks down to text a friend that he is running late. Just before he looks down. he is 80 m from an intersection, and a bicydist B, traveling at a constant speed of 10m/s,s d= 40 m from that same intersection. The light turns red during the 3 s text, and when the driver looks up, he hits the brakes, causing a constant deceleration of...
