I need help with 5 and 6 in 10 minutes. thank you

Instructions: For each questio or statement below, please cirele only one answer. need to follow the answer. The value traditional format for solving problems. Simply circle your each question or statement is 10 points. 5. Machines will always have frictional forces dissipate enervy forces, since frictional additional will be required to overcome these forces. Consequently, the efficiency of is always (B) than one (E) s to one 6. When the motion of one or both of the particles is at an angle to the line of impact, the impact is said to be (A) Central Impact (B) Oblique Impact (C) Eccentric Impact (D) Elastic Impact (E) None of the above. According to Newton's second law, momentum is conserved unless a body is acted upon by an extemal force such as gravity or friction.

Explanation / Answer

5) Option D

Efficiency of machine is always less than 1.

6) Oblique Impact

When motion is in line of impact, it is direct central imapct

When motion of one or both of particles is at an angle to the line of impact, the impact is oblique Impact.
