Answer:
Given:
mb=2.05 kgmb=2.05 kg Mass of the book
fs=2.45 Nfs=2.45 N Static friction
fk=1.50 Nfk=1.50 N Kinetic friction
Given,
Kinetic energy of the car = 2000 J
speed of the car is doubled
we know,
now, speed of the car is doubled
v' = 2 v
Using
=1/22
Hence, the Kinetic energy would be equal to 8000 J.
I'm going too hell for putting answers that are not really good enough for you but I need my answers and I need help with my answers
The momentum should be .5 because you multiply the mass and velocity to get momentum
Answer:
The correct answer is "6.96 rad/s".
Explanation:
The given values are:
Length,
L = 0.6 m
Mass,
m₁ = 0.5 kg
m₂ = 0.2 kg
Initial velocity,
V = 8 m/s
Now,
The final angular velocity will be:
⇒ 
By substituting the values, we get
⇒ 
⇒ 
⇒
