A rocket of mass 10000 kg, starting from rest, is acted on by a net force of 2 x 10 fifth power N for 20 sec. what is the final velocity of the rocket?

Sagot :

Rhyckayenviz
a=F/m
a=2×10∧5 N / 10000 kg
a=20 m/s²

final Velocity= initial velocity + (a×t)
V= Vo - at
V= 0 - (20m/s² × 20 sec)
V=400 m/s---> answer
