Why do we have to deflate the tires

of a car when it has to move on a

sandy road?

This is due to the the resistance that would be put up by the sand. The more you were to drive, the more resistance would be put up, causing the car to be stuck. By deflating the tires, they dont sink as deep into the sand, aka they don’t get as stuck, and deal with less resistance. :)

Explanation:

It also Roman Kumamoto states, “Essentially a car struggles to drive in loose sand because of inertia. Inertia is the tendency of a moving object to keep moving and a stationary object to remain stationary. Sand gets pushed away from a rotating tyre because the tyre finds it easier to move the sand away than to move the vehicle forward. Hopefully four rotating tyres become enough to swing the balance in our favour and generate enough momentum that we begin to move forward. We can easily swing the balance in our favour by the simple act of letting some air out of the tire’s.”

This proves my answer above :)

have a lovely day^^

conservation of mass

mass before something happens = mass afterwards

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
