initially at rest on the surface of Mars where g = 4 m/s ^ 2 . The mass of the spaceship is 3000 kg. The engines ignite and there is an upward thrust force on the spaceship . After a period of 25 seconds of constant thrust, the spaceship has reached a velocity of the 600 m/s.
A spaceship is initially at rest on the surface of Mars where g = 4 m/s ^ 2 . The mass of the spaceship is 3000 kg. The engines ignite and there is an upward thrust force on the spaceship . After a period of 25 seconds of constant thrust, the spaceship has reached a velocity of the 600 m/s.
what is the acceleration?
What is the altitude of the spaceship at 25 seconds?
We know that initially, the spaceship rests on the surface of mars and where g = 4 m/s2 and the mass of the spaceship is m, and after the time t, the velocity of the spaceship is v m/s.
So we know that the first equation of motion is given as
v=u+at ----------- eq1
where u is the initial velocity
a is the acceleration
t is time
We know that the second equation of the motion is given as
--------------- eq2
wheres is the altitude of the spaceship at the time t
