collides with another ball B of mass 10.0 kg which is initially at rest. After the collision A moves off with a speed of 1.0 ms−1 at an angle of 30º with its original direction of motion. Determine the final velocity of B.
speed is v and its distance from the centre of the Earth is R . If the eccentricity of its
orbit is 0.5, calculate its speed at the apogee.
2) 20 m/s , 3) 10*3^2 4) 20*3^2
How far away does the ball hit the ground? (in m to 2.s.f)
(note: ignore the effects of air resistance when solving this problem)
A) both will move right because the thief has a larger kinetic energy
B) both will move right because the thief has a larger mass
C) both will move left because the thief has a larger kinetic energy
D) both will move left because the thief has a larger mass
E) both will stop
and the centre of the base at the origin. If the density of the solid is given by the function
ρ(x, y,z) = xyz, determine the mass of the hemisphere.
