Explanation:
Range= U²sin2theta/g
= 102²* sin (2*42)/9.8
= 1054.74m
Yes she will be abable to jump
The distance from the edge will be
(1054.74- 420)m
= 634.74m
The increase in temperature of the water is
The total mass of the water is the product between its volume and its density
And so we can find the amount of heat released by the pebble to the water, because this is equal to the amount of heat absorbed by the water, which is
Tension may be defined as the pulling power transferred
axially through a cable, string, chain, or alike one-dimensional unceasing object,
or by separately end of a rod.
To compute for tension:
Sum the moments about the pivot:
ΣM = 0 = T * 3.5m * sin37 º - 45000N * 7.0m * cos37º
tension T = 119 434 N
