A device has a 100-g wooden shuttle that is pulled horizontally along a fixed frictionless wooden rail by an elastic band. The shuttle is released when the elastic band has 6.4 N tension at a 35º angle. What is the magnitude of the initial acceleration of the shuttle?

Plz make it clear with picture the angle is 35 or 45, I have solved it for 45.

Net force acting from band in horizontal direction=Tcos θ

=6.4 cos 45

=4.525 N

 Net acceleration=Force/mass in kg=4.525/0.100=45.25 m/s^2

If we take 35, we willl have ans 52 m/s^2

so the answer is 52 m/s 2  right ?
