Answer:
see that there is no dependence on speed, so the work remains constant
Explanation:
Work is defined by the expression
W = F. d
where the boldface indicates vectors, this equation can be written in scalar form
W = f d cos θ
where θ is the angle between force and displacement.
We see that there is no dependence on speed, so the work remains constant
The power is
P = W / t
P = f d / t
p = F v
we see that the power is the one that depends on the speed of the body
Then the workers that made poison for rats would have to throw all of the poison in the garbage, sad, I know. Oh, if rats was eliminated from the environment, then cats that LOVE rats wont be poisoned by the rats that EAT the poison :). Yes, one of my mama cats died );
Answer:
Explanation:
x(t) = (3.5 cm)cos[(0.8 rad/s)t]
Angular velocity ω = .8
Time period = 2π / ω
= 2 X 3.14 / .8
= 7.85 s
First time block will pass through equilibrium is T/4 ,
Second time block will pass through equilibrium
= 3.T/4
= 3/4 x 7.85
= 5.8875 s
