During launch, the SpaceX rocket engines provide an upward force (thrust) of 7.48 x 106 N. The mass of the rocket at this stage is 5.49 x 105 kg. If the rocket starts from rest, what is the velocity of the rocket at a height of 80 km above the surface of the Earth? Ignore air resistance. (Hint: Find the acceleration. Find v from the acceleration and distance: v(2 = v,2 + 2ad)iamanilkumawat Answered 24 minutes ago VF = 1476.466 m/s Explanation: upward Force F = 7-48 x10 N Solution : - 15- 49 X 105 kq mass M height 80km So First Find acceleration . Q = F 1 . 48 X 106 M 5 . 49 X 105 is this answer helpful
