Asked by Chad
A force of 50 N directed at an angle of 45 degrees from the horizontal pulls a 70 kg sled across a frictionless pond. The acceleration of the sled is most nearly (sin 45 degrees = cos 45 degrees = 0.7).

50 cos 45 = 35
f = m a
35 = 70 a
a = 35/70 = .5 m/s^2
f = m a
35 = 70 a
a = 35/70 = .5 m/s^2
