The mass of a spacecraft is about 435 kg . An engine designed to increase the speed of the spacecraft while in outer space provi

svlad2 [7]

Answer:

Δ v = 125 m/s

Explanation:

given,

mass of space craft = 435 Kg

thrust = 0.09 N

time = 1 week

= 7 x 24 x 60 x 60 s

change in speed of craft = ?

Assuming no external force is exerted on the space craft

now,

$T= m_s a$

$a=\dfrac{T}{m_s}$

$a =\dfrac{0.09}{435}$

a = 2.068 x 10⁻⁴ m/s²

using equation of motion

Δ v = a t

Δ v = 2.068 x 10⁻⁴ x 7 x 24 x 60 x 60

Δ v = 125 m/s
