If the coefficient of static friction between the coffee cup and the roof of the car is 0.20, what is the maximum acceleration the car can have without causing the cup to slide

a = 1.962 m/s²

Explanation:

The frictional force applied on the car can be given by the following formula:

where,

f = frictional force = ma (according to Newton's Second Law)

μ = coefficient of friction = 0.2

R = Normal Reaction = Weight of car = mg

Therefore, equation becomes:

where,

a = maximum acceleration = ?

μ = coefficient of friction = 0.2

g = acceleration due to gravity = 9.81 m/s²

Therefore,

a = 1.962 m/s²

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
