Explanation:

Sir Issac newton has given three laws of motion i.e.

1. First law of motion

2. Second law of motion

3. Third law of motion

The third law of motion states that, "If two objects collide, each object exerts a force equal to and in the opposite direction of the other". The applied force is called action force and its effect on another object is called reaction force. These two forces are applied on different objects. Mathematically, it is equal to :

F_{1,2}=-F_{2,1}

F_{1,2} is the force on object 1 due to object 2

F_{2,1} is the force on object 2 due to object 1

So, the correct option is (b) "If two objects collide, each object exerts a force equal to and in the opposite direction of the other".

A car is moving at 19 m/s along a curve on a horizontal plane with radius of curvature 49m.
JulsSmile [24]

Answer:

\mu =0.75

Explanation:

<u>Frictional Force </u>

When the car is moving along the curve, it receives a force that tries to take it from the road. It's called centripetal force and the formula to compute it is:

F_c=m.a_c

The centripetal acceleration a_c is computed as

\displaystyle a_c=\frac{v^2}{r}

Where v is the tangent speed of the car and r is the radius of curvature. Replacing the formula into the first one

F_c=m.\frac{v^2}{r}

For the car to keep on the track, the friction must have the exact same value of the centripetal force and balance the forces. The friction force is computed as

F_r=\mu N

The normal force N is equal to the weight of the car, thus

F_r=\mu .m.g

Equating both forces

\displaystyle \mu .m.g=m.\frac{v^2}{r}

Simplifying

\displaystyle \mu =\frac{v^2}{rg}

Substituting the values

\displaystyle \mu =\frac{19^2}{(49)(9.8)}

\boxed{\mu =0.75}
