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:
120
Step-by-step explanation:
Think about the eight letters A B C D E F G H, if A and B (or any two letters) are already chosen then you want to know how many ways 6 letters can fill 3 spaces when order matters, in other words the letters F G H are considered 1 outcome with the first two letters and G F H is considered another individual outcome with the first two letters. If order didn't matter then F G H and G F H with the first two letters would be considered only one outcome.
Answer:
Step-by-step explanation:
(3,4) and (3,-5)
y2 = -5 , y1 = 4, x2 = 3, x1 = 3
Slope m = (y2 - y1)/(x2 - x1)
m = (-5 - 4)/(3 - 3)
m = -9/0
Impossible. So no solution
Answer:
$38.50
Step-by-step explanation:
We are told the cost of the fabric per meter, so we first need to convert 250 cm into meters.
1 meter = 100 cm
Therefore, 250 cm = 250 ÷ 100 = 2.5 meters
cost of fabric = $15.40 per meter
To calculate the total cost, mulitply the length in meters by 15.40:
2.5 x 15.40 = 38.50
Answer: A. x-5
Step-by-step explanation:
3x/3= x
15/3= 5
