Question 2 Two cars are traveling toward each other. When they are 100 meters apart, the...
5. Two cars initially separated by 1000 m are traveling away from each other. Car A is moving at 20 m/s and is accelerating at 4 m/s'. Car B is moving at 10 m/s and is accelerating at 6 m/s. About how far (in meters) will Car A have traveled when the cars are 4000 meters apart? 6. A sailboat leaves a harbor and sails 1.8 km in the direction 65° south of east, where the captain stops for lunch....
Two cars are initially 21.50 km apart on a straight road. If the cars are moving toward each other, car 1 with a speed of 10.40 m/s and car 2 with a speed of 12.20 m/s, how many seconds will it take before the cars meet? Round your answer to three significant figures.
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...
Arthur and Betty start walking toward each other when they are 100.m apart. Arthur has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. Their dog, Spot, starts from Arthur's side at the same time and runs back and forth between them. By the time Arthur and Betty meet, what is Spot's displacement?
Two cars traveling toward each other on a single lane road at 16 m/s and 12m/s respectively when 120m apart both drivers realize the situation and apply their brakes. They succeed in stopping simultaneously and just short of colliding. Assuming a constant deceleration of each car, determine (a) time required for the car to stop (b) the deceleration of each car (c) the distance traveled by each car while slowing down.
Two cars are traveling along a straight line in the same direction, the lead car at 25.0 m/s and the other car at 28.0 m/s. At the moment the cars are 40.0 m apart, the lead driver applies the brakes, causing his car to have an acceleration of 2.00 m/s?. (a) How long does it take for the lead car to stop? (b) Assuming that the chasing car brakes at the same time as the lead car, what must be...
Two cars, side by side, start from rest one with an acceleration of 4 m/s^2. Both travel in some direction. How far apart 9 seconds later? In meters. 7m/s^2 is for second car
For
two objects with masses 100kg and 500 kg to be 20 meters apart,
find the gravity between them.
You can find their answers from the textbook (no need to turn in) 2) Turn in homework (Show Work, due to be announced): A 1000-kg car moves as speed from 10 m/s to 30 m/s in 20 seconds. What is the average speed? What is the acceleration? What is the average force acting upon it? If the car turns along a...
In an elastic collision two cars are traveling toward one another and crash head-on. The first car (A) has a mass of 700 kg and is traveling 20 m/s East and the second car (B) has a mass of 800 kg and is traveling 5 m/s West. After they collide, the first car (A) bounces backward at a rate of 15 m/s, what is the velocity of car (B) traveling at? A.0.625 m/s West B. 25.6 m/s East C. 25.6...
Two cars are traveling along a straight-line in the same direction, the lead car at 25.0 m/s and the other car at 36.0 m/s. At the moment the cars are 40.0 m apart, the lead driver applies the brakes, causing his car to have an acceleration of -1.80 m/s2. (a) How long does it take for the lead car to stop? (b) Assuming that the chasing car brakes at the same time as the lead car, what must be the...
