Answer:
The minimum distance needed to stop the car S = 36.68 meter
Explanation:
Mass of the car m = 1560 kg
Initial velocity u = 24
Final velocity v = 0
Coefficient of kinetic friction between the car tires and road is = 0.80
We know that acceleration of the car is given by
----- (1)
Where = Coefficient of kinetic friction between the car tires and road.
& g = 9.81
⇒ Acceleration a = 0.8 × 9.81 = 7.848
From the third law of motion
------ (1)
Negative sign is due to speed is decreasing of the car.
Put all the values in equation (1),
⇒ - 2 × 7.848 × S
⇒ 15.7 S = 576
⇒ S = 36.68 meter
This is the minimum distance needed to stop the car.
Gamma rays because it is a form of electromagnetic radiation. It has zero mass and no charge.
It won't happen anything i think it will just be a something like a small thing
