PHYSICS tension & angle

posted by .

A van accelerates down a hill (Fig. P4.71), going from rest to 30.0 m/s in 6.70 s. During the acceleration, a toy (m = 0.250 kg) hangs by a string from the van's ceiling. The acceleration is such that the string remains perpendicular to the ceiling.

Find theta

Find tension in the string
