Question

What is the approximate force of kinetic friction on a 50kg object sliding horizontally with a coefficient

of = 0.5
2. 5ON
b. 5OON
c. 25N
d. 250N

Answer 1

F = 250 N

Explanation:

Given that,

Mass of an object, m = 50 kg

The coefficient of kinetic friction = 0.5'

We need to find the force of kinetic friction. The kinetic friction is given by the formula as follows :

`F=\mu N`

N is normal force, N = mg

`F=0.5* 50* 10\\\\F=250\ N`

Hence, the force of kinetic friction is 250 N. Hence, the correct option is (d).
