Answer: The car was moving with the speed of 14.13 m/s.
Explanation:
Length of the skid marks,d = 34 m
Mass of the car = 825 kg
Coefficient of friction = 
Velocity of the car after applying the brakes =v
Acceleration due gravity = 
v = 14.13 m/s
The car was moving with the speed of 14.13 m/s.
First, we must find the power consumed by the light bulb. This is given by:
Power = voltage * current
Power = 250 * 0.8
Power = 200 W = 0.2 kW
Now, we must calculate the number of hours that the bulb is used, as the price given to us is in Rs/kWh. This is:
8 hours per day * 30 days
= 240 hours
Total kWh = 0.2 * 240
Total kWh = 48 kWh
Bill = 3 * 48
Bill = 144 Rs
<span>Newton established his three laws of motion to understand the motion of objects in a systematic way [ same thing as all Scientists did for human's curiosity ].
His three laws of motion are as follows:
First Law: - </span><span> An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Second Law: - </span><span> The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Third Law: - </span><span>For every action, there is an equal and opposite reaction
