An aircraft?starts at rest and is accelerated?at 13.2?m/s2 for 8.5 seconds, at which time the aircraft launches. What is the distance traveled from the starting point?to the launch point??Assume the acceleration is constant.
The ball strikes the floor at a speed of 7.8 m/s. Illustrate what was the initial speed of the ball? Assume that air resistance is negligible.
A stone is dropped into a river from a bridge at a height h above the water. Another stone is thrown vertically down at a time t after the first is dropped. Both stones strike the water at the same time. What is the initial speed of the second sto..
How high from the surface of the earth must an object be raised, What minimum speed is needed by the object to ascend to this height
Tim and Rick both can run at speed and walk at speed, with. They set off together on a journey of distance. Rick walks half of the distance and runs the other half. Tim walks half of the time and runs the other half.
An 8.5- {rm kg} point mass and a 15- {rm kg} point mass are held in place 50- {rm cm} apart. A particle of mass m is released from a point between the two masses 19- {rm cm} from the 8.5-{rm kg} mass along the line connecting two fixed masses.
Compute the x-coordinate of the center of mass XCM. Suppose that the mass of the rod is small enough to be ignored in your calculation. Your answers must be accurate to within 0.1 cm.
