A mass (m) rest on a frictionless slope within our physics lab room. The angle of the ramp with respect to the floor is 35 degrees. What is the magnitude of the mass's acceleration?

2 answers

well,the component of weight down the slide is mg*sinTheta

Force= mass*acceleration
mg*sinTheta=m*acceleration
solve for acceleration
Along the direction of motion, Newton's second law
(F = M a)
becomes
M g sin35 = M a
Therefore
a = g*sin35 = 5.6 m/s^2
