5. A motorboat starts from rest. Its motor provides a constant acceleration of 1 ft/s2 while...
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 =...
A car that starts from rest has a constant acceleration of 11 m/s2. How many meters does the car travel in the first 4.5 seconds?
A train starts from rest and starts with constant acceleration a = 3.6 m/s2 for 28 s. The train then coasts at constant velocity for 118 s. The train then comes to rest in 14 s. Please find the total distance covered by the train during the 160 s described. Kinematic equations: V = vo + at, x = x + vot + at", v = vi + 2aAx, x = x, + (v + v.)t.
The acceleration of a particle traveling along a straight path is a = 3 ft/s2 for 10 seconds. How far does the particle move in these 10 seconds, if it starts from rest? Report your answer in ft.
A streetcar in New Orleans starts from rest and has a constant acceleration of 1.20 m/s2 for 10.30 s. A.) Draw a graph to reflect If it has a constant acceleration of 1.20 m/s2 for 12.0 B.) Calculate how far has the streetcar traveled at the end of the 10.30 s? C.) Draw a graph to reflect if it has a constant acceleration of 1.20 m/s2 for 12.0
(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...
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...
The dragster starts from rest and has an acceleration described by the graph. a (ft/s2) 80 r (s)
The automobile is originally at rest at where s-0. If it then starts to increase its speed at dv/dt (0.05t2) ft/s2, where t is in seconds, determine the magnitudes of its velocity and acceleration whent- 18 s.
A car starts from rest and accelerates at a constant rate until it reaches 75 mi/hr in a distance of 220 ft, at which time the clutch is disengaged. The car then slows down to a velocity of 25 mi/hr in an additional distance of 570 ft with a deceleration which is proportional to its velocity. Find the time t for the car to travel the 790 ft.
