The velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.
<h3>
Velocity of the boy at the bottom of the slide</h3>
The velocity of the boy when he hits the water at the bottom of the slide is calculated from the principle of conservation of energy.
K.E = P.E
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is height of the boy
- g is acceleration due to gravity
v = √(2 x 9.8 x 10)
v = 14 m/s.
Thus, the velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.

Answer:
A = 4.76 x 10⁻⁴ m²
Explanation:
given,
weight of the person = 625 N
weight of the bike = 98 N
Pressure on each Tyre = 7.60 x 10⁵ Pa
Area of contact on each Tyre = ?
total weight of the system = 625 + 98
= 723 N
Let F be the force on both the Tyre
F + F = W
2 F = 723
F = 361.5 N
F = P A
A = 4.76 x 10⁻⁴ m²

The toxic effects of water pollution are generally very harmful for all living animals and plants. Numerous water borne diseases can effect animals and humans in the same way and can even lead to death. The toxic effects of water can make the temperature of the water rise. Also it can effect the conductivity and acidity of water.
