A big boulder has a mass of 8.20t (metric tons) and rests at a coal mine site. The boulder is blown up with explosives into 3 parts, all the 3 parts move horizontally in the xy plane. The biggest part (mass 3.3 t) travels west at a speed of 3m/s. The second part (mass 2.7t) moves at 2m/s in a direction 25.0 degrees south of east. What is the speed and direction of the third boulder part?

A 5.0 kg particle is moving with a velocity v(t) = (4.0î + 6.0tĵ) m/s. (Assume momentum is in kg · m/s, force is in newtons, and t is in seconds. Express your answers in vector form. Use the following as necessary: t. Do not include units in your answers.) What is the momentum (as a function of time) of this particle? What is the net force acting on this particle?

A star of mass M = 1.81 x 1030kg is the origin of a coordinate system. A comet of mass m = 7.87 × 10¹2 kg is initially at location = 2.49 x 10¹5 mî +3.88 × 10¹¹mj. The comet is travelling with velocity 7 = 3.68 × 10³ (The input below will accept answers with no more than 1% variation from the correct value.) Using conservation of energy and of angular momentum, what is the comet's distance from the star at the instant it's closest, and what is the comet's speed? (Hint: Consider the direction of the velocity relative to the position when the comet is at its closest point.) ×108m |T|= V ×105 m

The experiment done in lab is repeated, using a ball that has unknown mass m. You plot your data in the form of f 2 versus M/L, with f in rev/s, M in kg, and L in m. Your data falls close to a straight line that has slope 6.69 m/(kg · s2). Use g = 9.80 m/s2 and calculate the mass m of the ball.

Two friends are playing billiards at an arcade center. One guy hit the cue ball to strike at another ball where it is initially at rest. After the collision caused by the ball that was at rest, the cue ball moves at 2.50 m/s along a line making an angle e=14.0° with its original direction of motion and the second balI has a speed of 1.50 m/s. Find the answer for Part a,b and c. (Note: Both balls have the same mass.) Part A: Find the angle 0 between the direction of the motion of the second ball and the original direction of motion of the cue ball. Part B: Find the cue ball's original speed? Part C: Figure out whether kinetic energy is conserved?
