speed of 80 mi/hr? 2/11 Ball 1 is launched with an initial vertical velocity v1 = 160 ft/sec. Three seconds later, ball 2 is launched with an initial vertical velocity v2. Deter- mine v, if the balls are to collide at an altitude of 300 ft. At the instant of collision, is ball 1 ascending or descending?
Determine the speed of a satellite launched parallel to the surface of the earth so that it travels in a circular orbit 800 km from the earth’s surface.
2) The 3.22-1b particle A slides on the smooth horizontal plane and is connected to the spring by a cord which passes through a smooth hole in the plane. In the position shown, A has a velocity of 100 fps to the right as indicated, there is no slack in the cord, and the spring is unstretched. During the motion, the particle reaches a maximum distance of 10 ft from the hole. Determine the spring constant. Solve all questions using Impulse and Momentum methods
2. A footballer kicks a ball on horizontal ground giving it an initial velocity of 35 m/s at an angle of 25° to the horizontal. a. Where will the ball be 1.2 seconds after it is kicked? b. What will be the greatest height reached by the ball? c. Where will the ball land?
A communications satellite is in a circular orbit above the earth such that it always remains directly over a point on the earth’s surface. As a result, the period of the satellite must equal the rotation of the earth,which is approximately 24 hours. Determine the satellite’s altitude h above the earth’s surface and its orbital speed.
Watch out for that tree! George of the jungle is swinging on a vine and when he is at his lowest point in the swing he has a horizontal velocity of 15 m/s. At that moment his friend Ape the ape jumps onto George with a horizontal velocity of 4 m/s in the opposite direction that George is moving and they swing together until they hit a tree when they are 5m above the lowest point in the swing. The mass of George is 85 kg and the mass of Ape is 23 kg. With what velocity do they hit the tree?
The tethered ball is released from an initial position A with a given velocity and swings in a vertical plane. At the bottom position, the cord strikes the fixed bar at B, and the ball continues to swing in the dashed path. Calculate the velocity of the ball when in passes through point C (answer in m/s)
The two disks A and B have a mass of 4 kg and 6 kg , respectively. They collide with the initial velocities shown. The coefficient of restitution is e = 0.65. Suppose that (vA)1 = 6 m/s , (vB)1 = 7 m/s Determine the magnitude of the velocity of A just after impact. Determine the angle between the x axis and the velocity of A just after impact, measured clockwise from the negative x axis. Determine the magnitude of the velocity of B just after impact. Determine the angle between the x axis and the velocity of B just after impact, measured clockwise from the positive x axis.
A particle of mass m is projected from point A with an initial velocity v0 perpendicular to OA and moves under a central force F along an elliptic path defined by the equation r=r0 /(2 - cos 0) Using Eq. (12.35), show that F is inversely proportional to the square of the distance r from the particle to the center of force 0.
A ball is dropped from the top of a tower 80m high at the same instant a second ball is thrown vertically upward from the ground. If the two balls meet each other at the point of 44m above the ground, determine the initial velocity of the second ball.
At an amusement park in the greater area there are three 180-kg bumper cars occupied by seniors. The riders in cars A, B, and C have individual masses of 50, 70, and 40 kg respectively. Car A is observed to be moving to the right with a velocity v = 2 m/s and Car C is moving at vc = 1.5 m/s to the left. Car B is initially at rest with a collision imminent. The bumper cars are designed with a coefficient of restitution of 0.8 between each car, VC A B C Determine the final velocity of each car, after all impacts for the following two collision scenarios: (a) Cars A and Chit Car B at the same time, (b) Car A hits Car B before car C does (note there will be more than two total collisions)
