Answer:(3-8
Step-by-step explanation:
1. The force necessary to gain a velocity of 60 m/s within 5 mins is 40 N
2. The velocity gained by the object at the end of the second minute is 30 m/s
<h3>1. How to determine the force</h3>
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 60 m/s
- Mass (m) = 200 Kg
- Time (t) = 5 ms = 5 mins = 5 × 60 = 300 s
- Force (F) =?
F = m(v –u) / t
F = 200(60 – 0) / 300
F = 40 N
<h3>2. How to determine the velocity </h3>
- Force (F) = 150 N
- Mass (m) = 600 Kg
- Initial velocity (u) = 0 m/s
- Time (t) = 5 ms = 2 mins = 2 × 60 = 120 s
- Final velocity (v) = ?
F = m(v –u) / t
Cross multiply
m(v –u) = Ft
Divide both sides by m
v - u = Ft / m
v - 0 = (150 × 120) / 600
v = 30 m/s

Answer:
C: 56,72,52
Step-by-step explanation:
we know that
An acute triangle is a triangle with three angles less than 90°
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
<u><em>Verify each case</em></u>
case A) The three measures are less than 90 degrees but the sum is not equal to 180 degrees (is not a triangle)
case B) The three measures are not less than 90 degrees
case C) The three measures represent an acute triangle ( the three measures are less than 90 degrees and the sum is equal to 180 degrees)
case D) The three measures are not less than 90 degrees. This triangle represent a right triangle
