Abox is sliding down an incline tilted at a 11.1° angle above horizontal. the box is initially sliding down the incline at a speed of 1.60 m/s. the coefficient of kinetic friction between the box and the incline is 0.390. how far does the box slide down the incline before coming to rest?

s=0.68 m

Explanation:

Given

Inclination

Speed of block(u)=1.6 m/s

Coefficient of kinetic Friction

deceleration provided by friction=g\sin \theta -\mu _kg\cos \theta [/tex]

Using

Final velocity v=0

s=0.68 m

it doesn't. it was imagined up in the middle ages.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
