The projectile is shown at three points in its trajectory. At the highest point in its flight, the projectile breaks into three parts with masses as shown and velocities immediately after the break-up. Calculate all of the missing velocities, in m/s: Initial velocity before break up (V,x): Blank 1 Velocity of mass 3 (v3, f): Blank 2 Velocity of mass 2 (V2,f): Blank 3 What is the range of mass 2 from the launch point (need to calculate the height of projectile before break up): Blank 4 Ignore any effects due to air resistance and enter all answers to ONE DECIMAL PLACE, regardless of sig fig rules.

Given: ml=3.7 kg; m2=3 kg; Vli = 7 m/s; Vlf = 4 m/s; 0=25 degrees Find Velocity Vf2 and angle 0, y m Before collision After collision At rest Select one: Oa. 2.0849 @ 63.3930 degrees below horizontal Ob. 3.3298 @ 26.6070 degrees below horizontal Oc. 4 6552 @ 26.6070 degrees below horizontal

6. A 0.030-kg bullet is fired vertically into a 0.15-kg metal sphere that is initially at rest. If the bullet's velocity is at 200-m/s just prior to contacting the sphere and it is embedded within the sphere, how high up will the bullet/sphere rise relative to the initial location of the sphere? Answer: 57 m

An m = 6.90-kg clay ball is thrown directly against a perpendicular brick wall at a velocity of 22.0 m/s and shatters into three pieces, which all fly backward, as shown in the figure. The wall exerts a force on the ball of 2630 N for 0.110 s. One piece of mass m₁ = 2.90 kg travels backward at a velocity of 10.6 m/s and an angle of = 32.0° above the horizontal. A second piece of mass m₂ -1.90 kg travels at a velocity of 8.70 m/s and an angle of 28.0° below the horizontal. a) What is the speed of the third piece? Submit Answer Tries 0/99 b) What is the direction of the third piece? (Use positive values for an angle above the horizontal, and negative for below the horizontal.)
