HELP! A golf ball is struck with an initial speed of 15 m / s at an angle of 35 degrees above horizontal. What ...?
is the component Vertical golf ball initial velocity: * A.8.6 m / s b.9.8 m / s C. 12 m / m D.15 s / s Please answer the previous question. 21. A steel rod 40 m 50 ° C is heated to 100 ° C. What is the increased length of the rod since ? = 11 • 10-6 / K for steel: * mmmm c.0.044 b.0.022 A.0.011 d.40.022 Please answer the previous question. 22. A long solenoid cylindrical towers of 200 / cm with a current of 4.0 amps. The diameter of the solenoid is 0.40 cm and a length 8.0 cm and the mass of the moon is 7.35x10 ^ 22 kg. What is the magnetic field inside the solenoid: * A. 2.4x10 ^ T B. 16 T C. 0.26 T d. 2600 0.10 T Please answer to the previous question.
Sorry, I know that the first: Vo = 15 ? m / s = 35 ° = Vo I I * sin? = (15 m / s) * (sin35) I = (15 m / S) * (0574), part of the initial vertical velocity = 8.60 m / s
