Answer:
<em>The basketball player jumped 10 m high.</em>
Explanation:
<u>Vertical Launch Upwards
</u>
In a vertical launch upwards, an object is launched vertically up without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:

The basketball player jumps up with a speed of vo=14 m/s. The maximum height is:


The basketball player jumped 10 m high.
Answer:
The force between the Earth and the object is, F = 9.61 x 10⁻¹² N
Explanation:
Given data,
The mass of the Earth, M = 5.9 x 10²⁴ kg
The mass of the object, m = 10 kg
The gravitational force between the earth and the object is given by the formula,
F = G Mm/R²
Substituting the given values in the above equation,
F = 6.673 x 10⁻¹¹ x 5.9 x 10²⁴ x 10 / 6.4 x 10⁶
= 9.61 x 10⁻¹² N
Hence, the force between the Earth and the object is, F = 9.61 x 10⁻¹² N
Answer:
Explanation:
Let density of water be ρ .
During flow , volume of water flowing per second is constant
loss of P. E per unit volume = ρ gh , 83.5 % is lost
Gain of K E per unit volume = 1/2 ρ v²
83.5 % of mgh = ρ 1/2 ρ v²
1/2 ρ v² = .835 x 9.8
v² = 2 x .835 x 9.8
= 16.366
v = 4.04 m /s
