At first we have to find the time index, but you have to remember that time does not depend on mug's horizontal velocity. In this case : D=1/2∗g∗t2=1.18 where the in. velocity is 1.2/t.
Of course the mug velocity will be the same as previous one :
v=g*t
Then we have θ=tan−1(vy/vx) so that you can easily find what you need using trigonometry.
The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.
Given that,
Mass of the stone, m = 400 g = 0.4 kg
Initial speed, u = 20 m/s
It is climbed to a height of 12 m.
To find,
The work done by the resistance force.
Solution,
Let v is the final speed. It can be calculated by using the conservation of energy.
Work done is equal to the change in kinetic energy. It can be given as follows :
So, the required work done is 32.99 J.

Option B. Lava flowed from the moon
and I am pretty sure cause I have read about it and option B is the conclusion I came with lol :D
