The wave length becomes shorter and the pitch becomes higher
The aero plane would only move forward when the thrust force exceeds the drag force.
<h3>What is a projectile?</h3>
The term projectile has to do with a motion that follows a curved trajectory through air. The motion of an airplane that is dropping relief packages to flood victims is a good example of a projectile.
Excluding the horizontal and vertical forces, there are four important forces that act on the airplane;
- Drag force
- Gravity
- Lift
- Drag
- Thrust
The aero plane would only move forward when the thrust force exceeds the drag force.

Answer:
(a) The horizontal ground reaction force
(b) The vertical ground reaction force
(c) The resultant ground reaction force
Explanation:
Given
John mass , m = 65 kg
Horizontal acceleration ,
Vertical acceleration ,
(a) Using Newton's 2nd law in horizontal direction
=>
Thus the horizontal ground reaction force
(b) Using Newton's 2nd law in vertical direction
=>
=>
Thus the vertical ground reaction force
(c) Resultant ground reaction force is
=>
=>
Thus the resultant ground reaction force
