Q1. A 10.15 kg weather rocket generates a thrust of 177.03 N. The rocket, pointing upward, is clamped to the top of the vertical spring. The bottom of the spring, whose spring constant is 329.0 N/m, is anchored to ground. Originally, before the engine is ignited, the rocket sits at rest on top of the spring. After the engine is ignited, what is the rocket's speed when the spring has stretched 19.00 cm past its natural length? What would be the rockets speed after travelling the distance if it weren't tied down to spring?

Q2. The rms electric field of an electromagnetic wave increases from 278 to 874 N/C. find out the wave intensities for the two values of the electric field.
