Sunny_sXe [5.5K]

Answer:

41.0 m/s, 10.6 s

Explanation:

Given:

a = -4.8 m/s²

Δy = 165 m

v = -10.0 m/s

Find: v₀ and t

v² = v₀² + 2aΔy

(-10.0 m/s)² = v₀² + 2(-4.8 m/s²) (165 m)

v₀ = 41.0 m/s

Δy = vt − ½ at²

165 m = (-10.0 m/s) t − ½ (-4.8 m/s²) t²

165 = -10t + 2.4t²

0 = 2.4t² − 10t − 165

Solve with quadratic formula:

t = [ -(-10) ± √((-10)² − 4(2.4)(-165)) ] / 2(2.4)

t = (10 ± √1684) / 4.8

t = 10.6 s

A rocket ship has several engines and thrusters. While the Solid Rocket Booster (SRB) and main engines only work together during
Alexeev081 [22]

The acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

The given parameters;

  • <em>initial velocity of the engine, u = 1341 m/s</em>
  • <em>final velocity of the engine, v = 7600 m/s</em>
  • <em>time of motion, t = 2 minutes = 2 x 60 s = 120 s</em>

The acceleration of the SRB and main engine is calculated as follows;

a = \frac{\Delta v}{\Delta t } \\\\a = \frac{7600 - 1341}{2 \times 60  s} \\\\a = 52.16 \ m/s^2

Thus, the acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².
