Answer:
v = 8.49 m/s rounded off to 3 significant figures
Step-by-step explanation
Using Energy Conservation
U = Tk + Vp (Sum of kinetic Tk Energy and gravitational potential Vp Energy)
- At height = 3.67 m, the hammer was still or the velocity was negligible; hence, vi = 0 m/s.
- Ui = 0 + mgh
- At ground all potential energy is converted to kinetic; hence, Uf = mv².
- Since total energy of the system remains constant we equate Ui to Uf.
- Ui = Uf
- mgh = mv²
- After cancelling out masses and making v the subject of the formula we get:
v = = = 8.49 m/s rounded off to 3 significant figures
Answer:
42
Step-by-step explanation:
90 (the angle that was got split)
if the right side got 48 degree, simply find jow much is left on tge left side.
90 - 48 = 42°
