Answer:
a).11.546J
b).2.957kW
Explanation:
Using Inertia and tangential velocity
a).


Now using Inertia an w

average power=
b).
power=t*w
P=
P=2.957 kW
Answer:
KE=800,000
Explanation:
The formula for kinetic energy is KE=1/2mv^2 or Kinetic Energy= 0.5*mass*velocity^2
so 1000 is the mass and 40 is the velocity
KE=0.5*1000*40^2
KE=0.5*1,000*1,600
KE=800,000 Joules
Answer:
3,00,000
Explanation:
because 1 m =100m so, 3000x100=300000
