An image of a toy rocket and forces are shown below.
Assuming the only two forces on the toy rocket are lift and gravity, which of the following combinations would result in the rocket moving upward? A
Lift= 5 Newtons / Gravity = 5 Newtons B
Lift = 3 Newtons / Gravity = 4 Newtons C
Lift = 5 Newtons / Gravity = 4 Newtons D
Lift = 4 Newtons / Gravity = 4 Newtons
