Answer:
It is True
Explanation:.
A commander assigns a zone reconnaissance mission when he seeks additional information on a zone before committing other forces in the zone. It is appropriate when the enemy situation is vague, existing knowledge of the terrain is limited, or combat operations have altered the terrain. A zone reconnaissance could include several route or area reconnaissance missions assigned to subordinate units.
Answer: 4.24m/s²
Explanation:
Acceleration is defined as change in velocity of an object with respect to time. Mathematically,
Acceleration (a) = Change in velocity/time taken
Acceleration (a) = final velocity (v) - initial velocity (u)/time taken (t)
Final velocity = 700m/s
Initial velocity = 0m/s (object beginning from rest)
Time taken = 2.75mins = (2.75 × 60)secs = 165seconds
Substituting the values in the acceleration formula a = v-u/t
a = 700-0/165
a = 4.24m/s²
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
Answer:
first is regular reflection and 2nd is irregular
