The formula of the kinetic energy is KE = 0.5*m*v^2.
Given m = 80 kg and KE = 4000 J,
4000 = 0.5*80*v^2
v^2 = 100
v = 10 m/s
Answer:
16 m

The volume occupied by three milliliters of water is the same as three
cubic centimeters of water is true. The conversion is as follows.
3mL (1 L/1000 mL) (1 m3/1000 L) (100 cm/1 m)^3 = 3 cm3
Answer:
a) Image attached
b) It is acting CW
c) τ = 0.294N.m
Explanation:
As you can see in the image, the ruler will rotate clockwise.
For the total torque: τ = -W*(0.5 - 0.35) The distance used is from 35cm to 50cm
τ = -0.294N.m The magnitude is therefore: 0.294N
