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
