Compute all parts of given question:
Question: A projectile is launched with an initial speed of 32 m/s at an angle of 68° above the horizontal.
Part A: What is the magnitude of its velocity 2.0 s after launch? and
Part B: What is angle of its velocity 2.0 s after launch?
Part C: What is the magnitude of its velocity 5.0 s after launch?
Part D: What is the angle of its velocity 5.0 s after launch?
I need help to solve the above question and use the minus sign if the angle is below the horizontal.
