Answer:
Explanation:
mass of box, m = 60 kg
distance, d = 6.2 m
force, P = 150 N
coefficient of kinetic friction, μk = 0.21
work done by the gravitational force, Wg = Force x distance x cos 90
Wg = 0 J
Work done by the normal force, Wn = force x distance x Cos 90
Wn = 0 J
Work done by the friction force, Wf = - μk mg d
Wf = - 0.21 x 60 x 9.8 x 6.2 = - 765.58 J
Work done by the applied force, Wp = P x d
Wp = 150 x 6.2 = 930 J
Answer:
read a pleasant story to him Because if you threaten him meaning abusing him then you could go to jail for that if you read him a pleasant story to him then he will go to bed faster if you play an activity game he'll stay up longer and if you watch an exciting TV show he'll stay up longer too soon you just want him to go to bed sleep peacefully and that's why you read him a pleasant story So yeah my answer is read a pleasant story to him so he can go to bed and not be threatened or play an activity game or watch an exciting TV show if you want them to go to sleep That is why I put read a pleasant story to him
Russia and the United States sign the Moscow Treaty.
We Know, P = m*v
Here, m = 30 Kg
v = 5 m/s
Substitute it into the expression,
P = 30*5 Kgm/s
P = 150 Kgm/s
So, your final answer is 150 Kg.m/s
Hope this helps!
This would be true. On Jupiter you would weigh 234 pounds if you were 100 pounds on Earth.
