The airplane's speed relative to the ground is
√ (100² + 25²)
= √ (10,000 + 625)
= √ 10,625
= 103.08 km/hr .
The angle of its velocity north of west is
the angle whose tangent is (25/100)
arctan(25/100) = 14° north of west .
(bearing = 284°)

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
Is balancing .
Hope this is helpful
