Question

You happen to know that the coefficient of static friction between your patio table and the ground is 0.42. You decide you want to move it (45kg) by pushing on it. Are you able to move the table?

Answer 1

coefficient of friction is given as

`\mu_s = 0.42`

mass of the object is

`m = 45 kg`

now the maximum friction force on it given by

`F_s = \mu_s mg`

`F_s = 0.42 * 45 * 9.8`

`F_s = 185.22 N`

so here it is similar to hold a 18 kg mass in hand which is possible to hold

So here we can slide the box on the floor.
