The banking angle of the curved part of the speedway is determined as 32⁰.
<h3>
Banking angle of the curved road</h3>
The banking angle of the curved part of the speedway is calculated as follows;
V(max) = √(rg tanθ)
where;
- r is radius of the path
- g is acceleration due to gravity
V² = rg tanθ
tanθ = V²/rg
tanθ = (34²)/(190 x 9.8)
tanθ = 0.62
θ = arc tan(0.62)
θ = 31.8
θ ≈ 32⁰

The term for the principal that an object in motion remains in motion until it is met by an outside force is called inertia
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force .This principal is named as inertia .
Every matter have inertia , a property to remain in that very position until unless it is been forced on them to change their position .
Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true.

Answer:
The final velocity of 18 kg ball is 
= 42.09 
Explanation:
Mass of first ball 
= 18 kg
Mass of second ball 
= 47 kg
Initial velocity of 18 kg ball 
= 76
Initial velocity of 47 kg ball = 0
Final velocity of 18 kg ball = ??
Final velocity of 18 kg ball is given by the formula
= 
Put all the values in above formula we get
= 2 × 18 × 
= 42.09
Thus, the final velocity of 18 kg ball is = 42.09
Answer:
A beta emission(negatron)
Explanation:
1. A negatron resembles an orbital electron. It is represented as β⁻.
A negatron has a mass number of 0 but with a charge of -1
The decay of C-14 to N-14 can be depicted below:
¹⁴₆C → ¹⁴₇N + ₋₁⁰e
Both the mass number and atomic number is balanced according to the reaction.
2. In an electric field, the emission produced would be deflected towards the positive pole because it is negatively charged.
