1) ) A car is travelling at 37. m/ s. The driver hits their brakes and decelerates at 4.5 m/ s^2. How much distance does the car need to stop? 2) Suppose a child pulls a wagon horizontally. The child exerts a force of 51. N and there is frictional force of 18 N acting on the wagon, which opposes the motion. The mass of the wagon is 17.6 kg. (a) Draw a free body diagram for the wagon. (b)...
An 1800 kg car traveling at 35.0 m/s strikes a wall. If the car comes to rest in 0.500 seconds, then the magnitude of the average force of the wall on the car is
A car of mass 822 kg is traveling 25.4 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.67 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.) m/s2 (b)What magnitude force (in N) acted on the car during this time? N (c)How far (in m) did the car travel? m
Question 6 5 pts (5 points) A 2,500 kg car traveling at 20 m/s crashes into a 6,000 kg truck that is originally at rest. What is the speed of the truck after the collision, if the car comes to rest at the point of impact? (Neglect the effects of friction) O O m/s O 83 m/s 16.7 m/s O 8.33 m/s O none of the above
Please calculate and explain question (b).
(1 point) A car traveling at 80 km/h applies its brakes and comes to rest in 4.5 s. (a) Convert 80 km/h to units of m/s. 80 km/h 22.22 (b) Assuming a constant acceleration, calculate its value. acceleration 4.94 (c) How far did the car travel while the brakes were on? distance50 m/s m/s2
A car traveling at 22 m/s etrikes a tree. the front end compresses and the driver comes to rest after traveling 0.8 m. what was the acceleration of the driver during the collision?
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 car traveling 93 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.85 m . What was the magnitude of the average acceleration of the driver during the collision? Express the answer in terms of "g's," where 1.00g=9.80m/s2.
A 2500-kg car traveling at 6.0 m/s runs into a wall. The complete wall is not affected, but the car crumples such that in the time interval from the instant of impact to the instant at which the car comes to rest, the center of mass travels forward 0.4 meters. A) What is the magnitude of the average force exerted on the car? B) What is the time of the crumple?
Question 2 A car is traveling to the left at 20 m/s and it is accelerating to the left at a constant rate. After 5 seconds of time, the car is traveling to the right at 5 m/s. a. What is the acceleration of the car? b. How far does the car travel over the 5 seconds? Question 3 A stone is thrown upward. When the stone is traveling downward with a speed that is twice that of the initial...
