The velocity of a 2.5 kg block sliding down a frictionless inclined plane is found to be 1.58 m/s. 1.40 s later, it has a velocity of 7.32 m/s.
What is the angle of the plane with respect to the horizontal (in degrees)?
acceleration= change velocity/time
force down= mass*acceleration
solve for theta.
