The internal energy of a gas may be written U=C V nRT. I find that U(O 2)=3.285x10 7 J and U(H 2)=1.013x10 9 J before the ignition, so the initial internal energy of the system is U 1 =1.046x10 9 J. When ignition is complete, the energy added to the system is Q=44x286x10 3 =1.258x10 7 J and so U 2 =U 1 +Q=1.059x10 9 J.

The y-coordinate of a particle in curvilinear motion is given 3by y = 4t-3t, where y is in meters and t is in seconds. Also, the particle has an acceleration in the x-direction given by a x = 212t m/s . If the velocity of the particle in the x-direction is 4 m/s when t = 0, calculate the magnitudes of

Nov 10, 2020 · 2. A javelin thrown by an athlete., Consider a particle thrown up at an angle θ to the horizontal with a velocity u. The velocity of projection can be resolved into two component u cos θ and usinq along OX and OY respectively. The horizontal component remains constant while the vertical component is affected by gravity.

10 hours ago · Similar consideration of power balance during particle wrapping leads to an equation to determine the 3D speed factor α, where κ p = 1/R 1 + 1/R 2 = 2/R is the effective curvature of a spherical particle (1/R 1, 1/R 2 are the Gaussian principal curvatures) and.

At the later time, the projectile still has this horizontal component to its velocity, v x (since the horizontal speed of a projectile is constant). If we know that, and are given the new angle B, solving for the new overall speed at that time means solving for the hypotenuse of a right triangle where v x (=u*cos(A)) is the side adjacent to angle B.

A particle is projected with a speed u at an angle e with the horizontal. Find the radius of curvature of the parabola traced out by the projectile at a point, where the particle velocity makes an angle θ / 2 with the horizontal

An archer fires an arrow at an angle of 40° above the horizontal with an initial speed of 98 m/sec. The height of the archer is 171.5 cm. Find the horizontal distance the arrow travels before it hits the ground.

Well, gosh, you gotta get out of that armchair and learn something about the theory of special relativity. Your classically-based ideas of momentum and kinetic energy are wrong. In my discussion, I will call the rest mass of a particle m and the speed of the particle is v. Linear momentum is not mv but rather p=mv[1-v 2 /c 2]-1/2.

A heavy ball swings on a string in a circular arc of radius m. The two highest points of the ball's trajectory are Q and Q at these points the string is angle from the vertical.
