Answer:
f = -
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition f = - 19 when m = 14
- 19 = 14k ( divide both sides by 14 )
- = k
f = - m ← equation of variation
When m = 2 , then
f = - × 2 = -
The average force exerted by the block exists at -375 N.

How to find the average force exerted by the block?</h3>
Given:
Initial Velocity, u = 50m/s
Displacement, s = 10cm = 0.10m
Mass, m = 0.03Kg
Using the relation,
Substitute the values in the above equation, we get:
We know that, f = ma
Putting the values, we get:
f = (0.03)(-12500)
f = -375 N

Answer:
c
Step-by-step explanation:
Answer:94°
Step-by-step explanation:
The sum of the interior angles of the polygon: 180°(n-2)
180°(5-2)=540°
The sum of the interior angles of the pentagon is 540°
So:
P+Q+R+S+T=540°
(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°
4x+2+4x-10+5x-11+260=540
13x=299
x=23°
P=4x+2°=4×23°+2°=94°
