Answer:
W = 320.30 J
Explanation:
To calculate the net work done over the block you take into account all implied forces:
(1)
The gravitational force and friction force are against the applied force F.
θ = 26°
F: applied force = 340N
Fg: gravitational force = Mg = (40.0kg)(9.8m/s^2) = 392N
Ff: friction force = 
Next, you replace to obtain the net force:
Finally, the net work, for 4 m, is:
The answer is 10N. I hope that helps
The answer is D.An ice cube melts when a person holds it in his hand
The heat from your body is causing the ice cube to melt
Answer:
A=3.33m/s
B=3.11m/s
Explanation:
Speed = total distance/time taken to cover distance
hence,
S=d/t
s=32.0/9.60
s=3.33m/s
acceleration due to gravity
v=u+at
that is (v=final velocity,u=initial velocity,a=acceleration and t= time)
from the formula
2.10=32.0+a*9.60
2.10=32.0+9.60a
CLT
9.60a=32.0-2.10
9.60a=29.9
a=29.9/9.60
a=3.11m/s
hope it correct!?
