Show all work. Use units. Take g = 10 m/s2. 10 pts per question except as noted. Use 3 sig figs for all calculations. Ignore air resistance
A 55 kg person stands on a scale holding a 2 kg mass. Assume the scale responds instantly to changes in forces pushing on it.
The person now throws the 2 kg mass straight up with a throw that lasts 0.150 s. After the 2 kg mass leaves the thrower’s end, it makes a displacement of 75 cm to the apex.
14 Draw an FBD of the 2 kg mass immediately after it leaves the person’s hand on its way up to the apex.
15. Write Newton’s # 2 for the 2 kg mass from Q 14.
16. Use Q14 to solve to the acceleration of the 2 kg mass.
17. What is the scale reading at the same instant as Q14?
