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 travelin will it take for the cars to collide? g with a constant acceleration of -1.50 m/s2 a) Where...
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?
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...
ate, w change in the magnitude or direction of an objects direction, described 7). (15 points, bonus) An object is thrown vertically and has an upward velocity of 30 m/s when it reaches one 3/4 of its maximum height above its launch point. What is the initial (launch) speed of the object? . 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...
car moving along a straight section of road starts from rest, accelerating at 2.00 m/s? until it reaches a speed of 25.0 m/s. Then the vehicle moves for 87.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s (a) How long is the three-wheeled car in motion (in s)? (b) What is the average velocity of the three-wheeled car for the motion described? (Enter the magnitude in m/s.)...
A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...
A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550 m/s2. (a) What is the magnitude of its net linear acceleration 19.0 s later? (b) What angle does this net acceleration vector make with the car's velocity at this time? Question 6 A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550...
A ride-sharing car moving along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 32.0 m/s. Then the vehicle moves for 41.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the ride-sharing car in motion (in s)? 62 (b) What is the average velocity of the ride-sharing car for the motion described? (Enter the...
A train on a straight track starts from rest t station A. It accelerates for 20 seconds with an acceleration of 5 m/s^2 and then continues to travel at the velocity reached for two minutes. The train then decelerates at 5 m/s^2 for 20 seconds before coming to a stop at the next station B. What is the distance between the two stations?
A car starts out at the north end of a circular track 1.50 km in diameter and travels in a straight line to the east end and then travels in a straight line to the south end at a constant speed of 10.5 m/s. At the south end there is a straight road leading to the north end. The car starts from rest at the south end following the road and accelerates at 0.39 m/s2. (a)...
