Question

5. If 16,700 J of work is done to shoot the human cannonball down a 3.05 m barrel, then how much force is applied to the person to fire them out the cannon?

Answer 1

Answer:

5475.41N

Step-by-step explanation:

Work done = Force × distance

Given

Work done = 16700Joules

Distance = 3.05m

Required

Force

Substitute the given values into the formula as shown

16700 = Force × 3.05

Force = 16700/3.05

Force = 5475.41N

Hence the applied force is 5475.41N

Answer 2

The force required to apply to the person to fire them out of the cannon is required.

The force applied to the person to fire them out the cannon is 5475.41 N.

Force

W = Work done to shoot the person out of the cannon ball = 16700 J

s = Displacement of the person in the cannon = 3.05 m

F = Force applied to the person

Work done is given by

$W=Fs\\\Rightarrow F=\dfrac{W}{s}\\\Rightarrow F=\dfrac{16700}{3.05}\\\Rightarrow F=5475.409\approx 5475.41\ \text{N}$
