Question
A bullet is fired horizontally from a rifle at a distant target. Ignoring the effect of air resistance, which of the following is correct?
Options
A.Horizontal Acceleration → 10 ms-2
Vertical Acceleration → 10 ms-2
Vertical Acceleration → 10 ms-2
B.Horizontal Acceleration → 10 ms-2
Vertical Acceleration → 0 ms-2
Vertical Acceleration → 0 ms-2
C.Horizontal Acceleration → 0 ms-2
Vertical Acceleration → 10 ms-2
Vertical Acceleration → 10 ms-2
D.Horizontal Acceleration → 0 ms-2
Vertical Acceleration → 0 ms-2
Vertical Acceleration → 0 ms-2
Solution
In projectile motion Horizontal acceleration ax = o & Vertical acceleration ay = g =10m/s2
ax = 0
ay = 10 (down)
⇒ only ″C″ is correct Ans
ax = 0
ay = 10 (down)
⇒ only ″C″ is correct Ans
