# Question :   31. Three satellites launched into space connected together. Once in : 2102138

31. Three satellites are launched into space connected together. Once in deep space, an explosive charge separates the three satellites and they move apart. The satellites each have different masses with m1 < m2 < m3. Which of the following statements is always true?

A. The one with mass m1 receives the greatest impulse.

B. The one with mass m3 receives the greatest impulse.

C. The all must receive equal impulses.

D. Although one or more of the above statements could be true in special cases, they are not always true.

32. A 5.00-g bullet is fired into a 500-g block of wood suspended as a ballistic pendulum. the combined mass swings up to a height of 8.00 cm. What was the magnitude of the momentum of the combined mass immediately after the collision?

A. 6.25 ´ 10–3 kg·m/s

B. 6.25 kg·m/s

C. 0.632 kg·m/s

D. 0.394 kg·m/s

33. A 12.0-g bullet is fired into a 1 100-g block of wood which is suspended as a ballistic pendulum. The combined mass swings up to a height of 8.50 cm. What was the kinetic energy of the combined mass immediately after the collision?

A. 1.44 J

B. 1.86 J

C. 0.632 J

D. 0.926 J

34. A 5.00-g bullet is fired into a 900-g block of wood suspended as a ballistic pendulum. The combined mass swings up to a height of 8.00 cm. What was the kinetic energy of the bullet immediately before the collision?

A. 129 J

B. 23.3 kJ

C. 0.709 J

D. 0.355 J

35. A man standing on frictionless ice throws a 1.00-kg mass at 20.0 m/s at an angle of elevation of 40.0?. What was the magnitude of the man’s momentum immediately after throwing the mass?

A. 16.8 kg·m/s

B. 15.3 kg·m/s

C. 12.9 kg·m/s

D. This cannot be answered because the mass of the man needs to be known.
