The force of friction between an object and the surface upon which it is sliding is 14N and the coefficient of friction between them is 0.72. What is the weight of the object? 

Explanation:

Given parameters:

Acceleration = 0.0m/w

Initial velocity = 0m/s

Final velocity  = 00m/s

Unknown:

Distance traveled  = ?

Solution:

To solve this problem, we use the expression below:

    q0   = y   + 0w

W is the final velocity

Y is the initial velocity

C is the acceleration

P is the distance

          0²  = 0²   +  (0 x 0.0 x S)

          000  = 00.0S

            S = 0m

object 2 because all the other ones are wrong

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
