A three-wheeled car moving along a straight section of road starts from rest, accelerating at 2.00 m/s² until it reaches a speed of 26.0 m/s. Then the vehicle moves for 77.0 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...
8. A car (mass - 1221 kg) is moving along a straight, level road at a constant speed of 8.95 m/s. The car then speeds up to 35.6 m/s in 12.4 s. a. How much work was done on the car during this time? b. What was the average power supplied to the car while it was speeding up?
A railroad handcar is moving along straight, frictionless tracks with negligible air resistance. In the following cases, the car initially has a total mass (car and contents) of 160 kg and is travelling east with a velocity of magnitude 5.20 m/s. Find the final velocity of the car in each case, assuming that the handcar does not leave the tracks. An object with a mass of 22.0 kg is thrown sideways out of the car with a speed of 1.60...
any help would be great! A car is moving along a straight road. At time t seconds, the position of the car (in feet) is s(t) = 51. Find the average velocity of the car over the time intervals given below. (a) t = 11 to t= 11.1 seconds (b) t = 11 tot = 11.01 seconds (c) t = 11 to t = 11.001 seconds (a) The average velocity of the car over the time interval from t =...
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...
6. Two cars are traveling along a straight road. Car (A) maintains a constant speed of 90.0 km/h; car (B) maintains a constant speed of 101 km/h. Att 0, car (B) is 45.0 km behind car A. How far will car (A) travel from t 0 before it is overtaken by car (B)? km 7. A ball is thrown vertically downward from the edge of a bridge 30.0 m high with an initial speed of 100 m's. The ball all...
6. Two cars are traveling along a straight road. Car (A) maintains a constant speed of 80.0 km/h; car (B) maintains a constant speed of 115 km/h. At t = 0, car (B) is 31.0 km behind car A. How far will car (A) travel from t-0 before it is overtaken by car (B)? km 7. A ball is thrown vertically downward from the edge of a bridge 25.0 m high with an initial speed of 18.0 m/s. The ball...
