What is force?</h3>
Force can be defined as the influence that can accelerate the object. From Newton's Second Law of motion,

Where,
- force
- mass = 0. 25 kg
- acceleration = 5 N
Put the values in the formula,

Therefore, the force exerted on Alice’s foot as she kicks the ball is 1.25 N.

Answer:
0.063
Explanation:
velocity of the car, v = 40 km/h = 11.11 m/s
radius, r = 200 m
Let the coefficient of friction is μ.
The coefficient of friction relates to the velocity on banked road is given by

where, v is the velocity, r be the radius of the curve road and μ is coefficient of friction.
By substituting the values, we get

μ = 0.063
