Are silent run on power and have to be electricly charged
The change in velocity that occurs within an interval of time is known as ACCELERATION.
Acceleration is the rate of change of velocity with time. It is a vector quantity. The rate of change of velocity can be positive or negative. The positive change of velocity is called acceleration while the negative change in velocity is called deceleration.

Answer:
Explanation:
Given
height of building h=3 m
Landing velocity of diver at an angle of
Let u be the initial velocity of diver at an angle of \theta with horizontal
Since there is no acceleration in horizontal direction therefore horizontal component of velocity will remain same
---- -----1
Considering Vertical motion
here
----------------2
Divide 2 and 1 we get
Thus
From the geometry of the problem, the 20 m-long cable creates
the hypotenuse of a right triangle, with the extended of the other two sides of
size 20 m * cos(30 deg), which is around 17.3 m. Therefore, the ball has increased
by 20 m - 17.3 m = 2.7 m.
The potential energy will have altered by m*g*h, which is 1400 kg * 9.8 m/s^2 *
1.6 m , or about 37044 joules.
