b) If the shot-put has a mass of 20 kg and is launched at an initial velocity of 15m/s at an angle of 42°, how long will it take for the shot-put to return to the same vertical height as it started at? Hint: what is the displacement in the y-dimension? c) How long does it take for the shot-put to reach its maximum height? d) What is the velocity of the shot-put at the maximum height along the trajectory?

Question
Answer questions 4A, 4B, 4C, 4D and 4E. Please show work!!
Question for 4E is: If you launch a 40 kg shot-put with the same angle and initial velocity. How do the values in B through D change?
Transcribed Image Text:b) If the shot-put has a mass of 20 kg and is launched at an initial velocity of 15m/s at an angle of
42°, how long will it take for the shot-put to return to the same vertical height as it started at? Hint:
what is the displacement in the y-dimension?
c) How long does it take for the shot-put to reach its maximum height?
d) What is the velocity of the shot-put at the maximum height along the trajectory?
Transcribed Image Text:4a) A shot-put is thrown. For the each of the indicated positions of the shot-put along its trajectory, draw
and label the following vectors: the x-component of the velocity, the y-component of the velocity, and the
acceleration. Explain why you drew the vectors as you did.
