In an experiment in space, one proton is held fixed and another proton is released from rest a distance of 2.50 mm away.. What is the initial acceleration of the proton after it is released. Please explain where you find the numbers to plug in the formula that is what is really confusing such as the mass and charge because it does not mention it in the question. I know were going to use F=ma and F=kq/r^2 but there are...

7. In an experiment in space, one proton is held in a fixed position. Then a second proton is point) released from rest at a distance of 2.50 mm from the fixed proton. What is the initial acceleration of the proton after it is released? O2.20 x 104 m/s 0 8.80 x 106 ms 2.45 x 10-6m/s2 O2.53 x 108 m/s2 m's

2. Artificial gravity is necessary for humans to stay healthy during extended stays in space. To provide artificial gravity, a space station is shaped like a cylinder with a diameter of 2200 m, and it rotates about its center at a constant rate. The astronauts live inside the cylinder at the outer edge, and feel a gravitational pull outwards. (a) How long should one revolution of the space station take if the acceleration of an astronaut on the outer edge...

A bullet with mass 25g and initial horizontal velocity 320m=s strikes a block of mass 2kg that rests on a frictionless surface and is attached to one end of a spring. The bullet becomes embedded in the block. The other end of the spring is attached to the wall. The impact compresss the spring a maximum distance of 25cm. After the impact, the block moves in simple harmonic motion. 1. What is the frequency of the oscillation? 2. Sketch graphs...

1. A proton travels directly (head on) towards a stationary lead nucleus, with an initial speed v0, when the proton is a distance x0 from the nucleus. It undergoes an acceleration of magnitude a = kx−2 directed away from the nucleus, where x is the distance from the proton to the nucleus and k is a positive constant. (Assume the lead nucleus remains stationary throughout.) (a) Give an expression for how the velocity of the proton depends on x. (It...
Allison throws a tennis ball at time t = 0 from a height h above the...
Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...

1. Teresa Drops a Stone. (Allotted Time - 40 minutes) Teresa drops a stone from rest from the top of an extremely tall building on a huge planet with essentially no atmosphere. You may assume that the stone experiences a constant gravitational acceleration as it falls to the planet’s surface, but the magnitude of this acceleration may not be equal to that on Earth. Let d1 be the distance the rock travels during the 1st second of its fall, let...
