The are elements on the periodic table
Acceleration required to stop rocket:
2as = v² - u²
a = -(18)²/(2 x 265)
a = 0.61 m/s² upwards
Resultant force = mass x acceleration
Resultant force = upwards thrust - weight
1.14 x 10⁴ x 0.61 = Thrust - 1.14 x 10⁴ x 1.6
Thrust = 2.52 x 10⁴ Newtons
A ) <em>Speed</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>scalar quantity and velocity is a vector quantity.</em>
