the space shuttle engines cause an upward force of 3 x 10 ^5 N to act on the shuttle. gravity pulls down on the shuttle with a force of 1.96 x 10^5 N. what is the net force on the shuttle? what is the direction of the net force?
same as the other question
(3-1.96)10^5 Newtons up
To find the net force on the space shuttle, we need to calculate the difference between the upward force caused by the shuttle engines and the downward force due to gravity.
The upward force caused by the space shuttle engines is given as 3 x 10^5 N.
The force of gravity pulling down on the shuttle is given as 1.96 x 10^5 N.
To find the net force, we subtract the downward force (gravity) from the upward force (engine thrust):
Net force = Upward force - Downward force
Net force = (3 x 10^5 N) - (1.96 x 10^5 N)
Calculating the net force:
Net force = 1.04 x 10^5 N
Therefore, the net force on the shuttle is 1.04 x 10^5 N, directed upward.
Explanation: In this case, we find the net force by calculating the difference between the two forces acting on the shuttle. The upward force exerted by the space shuttle engines is greater than the force of gravity pulling the shuttle down. Since the net force is positive, it means there is an overall upward force acting on the shuttle.
