<span>A. Rocket A will travel farther horizontally than rocket B.
This is because from the x axis, 40 m/s at 90 degrees travels directly vertical. 40 m/s at 70 degrees is slightly horizontal, so it will travel further horizontally.</span>
Answer:
25 x 9/5 = 45 degrees Fahrenheit
Explanation:
Answer:
2.12 J
Explanation:
Initial kinetic energy = final elastic energy + work by friction
KE = EE + W
KE = ½ kx² + W
5 J = ½ (1600 N/m) (0.06 m)² + W
W = 2.12 J
