A 2.2-kg model rocket is launched vertically and reaches an altitude of 70 m with a speed of 30 m/s at the end of powered flight, time t = 0. As the rocket approaches its maximum altitude it explodes into two parts of masses mA = 0.77 kg and mB = 1.43 kg. Part A is observed to strike the ground 80 m west of the launch point at t = 6 s. Determine the position of part B at that time.

Answer:
Explanation:
given,
mass = 2.2 kg
altitude(r₀) = (70 j) m
speed = 30 m/s
m_a = 0.77 kg
m_b =1.43 kg
part A strike ground (r_a)= (80 i) m
t = 6 s
r = 63.6 j m
by conservation of energy
