(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...
Air Force One accelerates from rest at a constant rate of 5.80 m/sec^2 along a runway that is 3.47 km long. Assume that the plane reaches takeoff speed exactly at the end of the runway. a) what is the time needed to take off? b) What is the speed of the plane as it takes off?
A speedboat starts from rest with a constant acceleration of +1.50 m/s2. After 4.00 seconds, its acceleration changes to +1.00 m/s2. After another 5.00 seconds, its acceleration changes to zero and the boat travels with constant velocity for a further 10.0 seconds. The boat then slows down and stops by accelerating at -2.00 m/s2. 1. Calculate the velocity and displacement of the boat at t = 4.00 seconds. 2. Calculate the velocity and displacement of the boat at t =...
5. A car starting from rest moves in a straight line with a constant acceleration of 1.90 m/s2 for 14.0 s, then slows down to a stop with a constant deceleration of 2.60 m/s2. How far does it travel? X Blank meters 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 falls all the way down and strikes the water below. Determine the time...
An airplane reaches its takeoff speed of 60 m/s with constant acceleration in 30 s, starting from rest. The time it takes to go from 40 m/s to 60 m / s is: A car starts moving from rest with an acceleration of 0.40 m/ s2. A minute later the acceleration stops, and the car moves with constant speed for 5.0 minutes. The car's brakes are finally applied and stops in 2.0 minutes slowing evenly. The total distance traveled by...
1. A jet plane has a takeoff speed of ? = 75 m/s and can move along the runway at an average acceleration of 1.3 m/s2. If the length of the runway is 2.5 km, will the plane be able to use this runway safely? Defend your answer. 2. A person takes a trip, driving with a constant speed of 89.5 km/h, except for a 22.0 min rest stop. If the person’s average speed is 77.8 km/h, (a) how much...
