Answer:
47 ms
well the time it takes to fall 100m is the same time it takes to travel 65m horizontally.
The time to fall vertically, t is sqrt(2d/g). [this comes from d = 1/2at^2]
so t = sqrt(2*100/9.8) = 4.52s.
The vertical speed at that time is g*t = 9.8*4.52 = 44.3m/s
The horizontal speed is the horizontal distance over the same 4.52s, = 65/4.52 = 14.4m/s.
so the final velocity is = sqrt(44.3^2 + 14.4^2) = 47.ms
Answer:upper right hand side i think
Explanation:
In hot warter or substant bc hot makes molecues go,s faster then all the rest
Both kinetic and potential. Kinetic as it is moving and Potential due to its relative position to the ground, in this case it is in the air, elevated from the ground.
