Answer:
<h2>7.2 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>7.2 J</h3>
Hope this helps you
Answer:
The final speed will be 8.02 rad/s.
Explanation:
Given that
radius ,r=5.9 m
Total acceleration = 18
Tangential acceleration = 12
Here particle is moving in circular path with varying linear speed.So there will be two acceleration ,one is radial acceleration and other one is tangential acceleration.
12=α x 5.9
ω=2.2 rad/s
θ=2πn
θ=2 x π x 1/8 rad
θ=π /4 rad
So the final speed will be 8.02 rad/s.
Answer:
A heat engine is a device that converts internal energy into work. Internal energy is increased by the addition of heat. The efficiency of a heat engine is a measurement of how efficiently it works. Efficiency compares the amount of useful energy extracted from a process to the total energy input. The heat engine will be more efficient if the percentage is higher.
