8). (15 points) Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.50 m/s2. This car moves toward a second car that is 32.0 m away. The second car is moving away from the first car and is traveling at a constant speed of 4.50 m/s. a) Where will the cars collide? b) How long will it take for the cars to collide?

7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00 m/s2. This car A moves toward the car B that is 25.0 m away. The car B is moving in same direction as car A with an initial velocity of 4.5 m/s and is traveling with a constant acceleration of -1.50 m/s2 a) Where will the cars collide? b) How long will it...

→XCIO D Question 11 7.5 pts An object moves in the x direction only under a constant acceleration. It's acceleration is 3 m/s in the *x direction. It is originally moving at 14 m/s in the direction. How long does it take in seconds, to travel a displacement of 22 m in the ex direction? Hint: Find the velocity at this displacement similar to the last question, first.

Answer in units of m/s. Fo tic av 012 10.0 points An object is thrown vertically up and attains an upward velocity of 50 m/s when it reaches one fourth of its maximum height above its launch point. What was the initial speed of the object? The acceleration of gravity is 9.8 m/s.

is ball on Moon, where the acceleration due to gravity is 1/6(g -9.8) and air resistance is negligible, is hit directly upward and returns to the same level 85 s later, (a) How high above its origjinal point did the ball go? (b) How fast it moving just a after it was hit? 7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00...

At time t = 0 s, a rock is thrown vertically upward from the ground. At time t = 1.6 s, it passes the top of a tall tower. 0.80 s later, it reaches its maximum height. Q)How fast is the rock moving as it passes the top of the tower? A car moving with constant acceleration covers the distance between two points 120 m apart in a time of 8.0 s. Its speed at the second point is 12...

14. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs vertically and one mass slides on a frictionless 30.0 degree incline. The vertically hanging mass is 6.00 kg and the mass on the incline is 4.00 kg. The magnitude of the acceleration of the 4.00 kg mass is 15. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs...

11. ssm A bicyclist makes a trip that consists of three parts, each in the same direction (due north) along a straight road. During the first part, she rides for 22 minutes at an average speed of 7.2 m/s. During the second part, she rides for 36 minutes at an average speed of 5.1 m/s. Finally, dur- ing the third part, she rides for 8.0 minutes at an average speed of 13 m/s. (a) How far has...
