A proton (mass m = 1.67 x 10-27 kg) is being accelerated along a straight line at 5.60 x 1012 m/s2 in a machine. If the proton has an initial speed of 1.10 x 105 m/s and travels 2.80 cm, what then is (a) its speed and (b) the increase in its kinetic energy? (a) Number Units (b) Number Units The number of significant digits is set to...

Flying Circus of Physics On August 10, 1972, a large meteorite skipped across the atmosphere above the western United States and western Canada, much like a stone skipped across water. The accompanying fireball was so bright that it could be seen in the daytime sky and was brighter than the usual meteorite trail. The meteorite's mass was about 3.9 x 106 kg; it's speed was about 15 km/s....

The figure gives the acceleration of a 3.0 kg particle as an applied force moves it from rest along an x axis from x = 0 to x = 9.0 m. The scale of the figure's vertical axis is set by as = 8.0 m/s2. How much work has the force done on the particle when the particle reaches (a) x = 4.0 m, (b) x = 7.0...

A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.30 x 10-3 s, and the force of the kick is given by F(t) = [(9.69 x 105) - (7.45 x 103)+2] N for osts 1.30 X 10's, where t is in seconds. Find the magnitudes of the following: (a) the impulse...

A 28 kg body is moving through space in the positive direction of an x axis with a speed of 260 m/s when, due to an internal explosion, it breaks into three parts. One part, with a mass of 17 kg, moves away from the point of explosion with a speed of 140 m/s in the positive y direction. A second part, with a mass of 3.6 kg,...

In the figure below, a 4.0 kg block is accelerated from rest by a compressed spring of spring constant 600 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction uk= 0.30.The frictional force stops the block in the distance of D = 8.0 m. -- No friction a) Find the increase in the thermal energy of the block-floor system b) What is the original compression...

Chapter 07, Problem 062 A 190 g block is dropped onto a relaxed vertical spring that has a spring constant of k-5.0 N/cm (see the figure). The block becomes attached to the spring and compresses the spring 17 cm before momentarily stopping. While the spring is being compressed, what work is done on the block by (a) the gravitational force on it and (b) the spring force? (c) What is the speed of the block just before it hits the...
