Answer:
I'm so sorry!!! I don't understand how you are supposed to do this problem... I hope someone can help you out. Have a good day
Step-by-step explanation:
Super sorry
From the equation of motion, we know,
Where s= displacement
u= initial velocity
a= gravitational force
t= time
Displacement is 0 since the ball comes back to the same point from where it was thrown.
A = 
since the ball is thrown upwards.
Plug the known values into the equation.
=> 
Solving for u gives :
u= 16.67 m/ sec ....... equation (1)
At maximum height, final velocity i.e v is 0
Time take to reach the top = 
=> 
Solving for s we get
s= 14.16 m
Answer:
3 1/2
Step-by-step explanation:
Answer:
I think it goes like this : 20:4=5 so there's five monsters in the room
Step-by-step explanation:
if that's the case of this question it should go like this:
9(rooms)×5(monsters per room)= 45 monsters
30(monsters):5(monsters per room)=6 rooms
13(rooms)×5(monsters per room)=65 monsters
35(monsters):5(monsters per room)=7 rooms
I hope you do well in your assignment.
I hope I helped at least a little!
