Answer:
Part a)
Part b)
Explanation:
Part a)
Since the diver is moving under gravity
so here its acceleration due to gravity will be uniform throughout the motion
so here we will have
here we have
Part b)
at highest point of his motion the final speed will be zero
so we will have
In order for the object to move upward, it needs an upward force
that's at least equal to its own weight.
Weight = (mass) x (gravity) = (35 kg) x (9.8 m/s²) = 343 N.
The engine thrust has to be more than 343 N.
The property that does not describe an acid is that it has a bitter taste. Acids have a sour taste, Bases have a bitter taste.
