A bullet (m = 0.0270 kg) is fired with a speed of 99.00 m/s and hits a block (M = 2.60 kg) supported by two light strings as shown, stopping quickly. Find the height to which the block rises.(adsbygoogle = window.adsbygoogle || []).push({});

I found this by conservation of energy, the answer was .0528 m

Find the angle (in degrees) through which the block rises, if the strings are 0.280 m in length.

I tried doing this using trig.

the hypotenuse= .280 m

opposite = (.280-.0528) = .2272 m

adjacent= x

sin^-1 (.2272/.280)= 54.2 deg.

What am I doing wrong?
