a=g•tanθ
T= sqrt{(ma)²+(mg)²}=
=m•sqrt{a²+g²}
A mass M = 40.0 kg is suspended by a massless string from the ceiling of a van which is moving with constant acceleration a, as shown in the figure. If the string makes an angle theta = 21° with respect to the vertical, what is the acceleration a of the van?
What is the tension in the string?
