Homework Statement
A block is pushed across a horizontal surface with a coefficient of kinetic friction of 0.15 by applying a 150 N horizontal force. The block accelerates at 2.53 m/s^2. Find the mass of the block.
Homework Equations
ƩF = ma
The Attempt at a Solution
μk = 0.15
Fa (applied force) = 150 N
a = 2.53 m/s^2
m = ?
I understand I must find the frictional force first, correct?
and Ff (frictional force) = μFN (normal force)
And to find normal force, FN = mg
but then I come across this, which also requires for me to find mass...?
What can I do?
