The figure shows a two-ended "rocket" that is initially stationary on a frictionless floor, with its center at the origin of anxaxis. The rocket consists of a central block C (of mass M-7.90 kg) and blocks L and R (each of mass m -2.60 kg) on the left and right sides. Small explosions can shoot either of the side blocks away from block C and along the x axis. Here is the sequence: (1) At time t-0, block Lis shot to the left with a speed of 3.40 m/s relative to the velocity that the explosion gives the rest of the rocket. (2) Next, at time t - 0.80 s, block R is shot to the right with a speed of 3.40 m/s relative to the velocity that block C then has (after the second explosion). At t -2.70s, what are (a) the velocity of block C (including sign) and (b) the position of its center? (a) Number (b) Number i-0.172 0.21 Units Units m/s m С R

The figure shows a two-ended "rocket" that is initially stationary on a frictionless floor, with its center at the origin of an x axis. The rocket consists of a central block C (of mass M = 5.10 kg) and blocks L and R (each of mass m = 1.30 kg) on the left and right sides. Small explosions can shoot either of the side blocks away from block C and along the x axis. Here is the sequence: (1) At time t = 0, block L is shot to the left with a speed of 3.40 m/s relative to the velocity that the explosion gives the rest of the rocket. (2) Next, at time t = 0.80 s, block R is shot to the right with a speed of 3.40 m/s relative to the velocity that block C then has (after the second explosion).

A 78.9 kg linebacker (X) is running at 6.83 m/s directly toward the sideline of a football field. He tackles a 89.1 kg running back (O) moving at 9.27 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?fvf of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?

A woodblock of mass Mw = 200 g is projected from the ground at a speed v0 = 35 m/s and at an angle, θ0 = 50º. When at height h = 24 m the woodblock was hit by a bullet of mass Mb = 25 g which was moving at vb = 220 m/s and at an angle θb = 70º. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground. Then they move on the ground that has a coefficient of kinetic friction µk = 0.5 and starts to compress a horizontal spring at point B. The distance between point A and B is 18 m and the spring constant k = 3×10^2 N/m. The right end of the spring is fixed, and all motions are confined in x-y plane.
