A 1300-kg rocket has a net propulsion force of 50 kN (kiloNewtons). Over a short time period, it uniformly speeds up from an initial velocity of 35 m/s to a final velocity of 60 m/s. Assume that the mass of the rocket is constant during this time period and that the net force is along the direction of motion. What is the change in speed of the rocket in m/s and in mph? m/s mph Submit Answer Tries 0/2 What...

Learning Goal: To understand
the relationship between force, impulse, and momentum. The effect
of a net force ΣF⃗ acting on an object is related both to the force
and to the total time the force acts on the object. The physical
quantity impulse J⃗ is a measure of both these effects. For a
constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse
is a vector pointing in the same direction as the force vector. The
units...
