You can't see beyond a blind turn, so a mirror would allow you to see around the corner.
Answer:
Part a)
Part b)
Part c)
Part d)
Explanation:
Part a)
Since the gymnast is holding the rope and remains stationary
So total force is balanced on it
so we will have
T = mg
Part b)
Now gymnast start climbing the rope at uniform speed
so here we have
so again we will have same force equation
Part c)
Now gymnast start climbing up the rope at uniform acceleration
so now we will have
Part d)
Now gymnast start sliding downwards with same uniform acceleration
so now we will have
now we have
The large can of solids will reach before the empty can reason being is it has more additional weight its like dropping a 1 pound weight compared to a 4 pound the 4 pound reaches faster because of the gravitational pull the size of the pull depends on the masses of the objects
Answer: 5 m, 2 s
Explanation:
gravity is roughly 10 m/s²downward
That means in one second, the velocity will have been reduced to zero
The average speed is (10 + 0) / 2 = 5 m/s
h = vt = 5(1) = 5 m
It will take as long to fall back to the thrower from rest so total flight is 1 + 1 = 2 s
