A10n force is applied to a 25kg mass to slide it across a frictional surface. what is the acceleration of the mass?

Force (in Newtons) equals mass (in kilograms) times acceleration (in meters per second squared).

Plug in the given force and mass to the equation and solve for acceleration:

10=25a

0.4m/s2=a

Hope this helps!!

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
