Question

A bullet is fired straight up from a gun with a

muzzle velocity of 167 m/s.
Neglecting air resistance, what will be its
displacement after 3.8 s? The acceleration of
gravity is 9.8 m/s
2
.
Answer in units of m.

Answer 1

v(4 seconds)= 300 m/s - 9.8 (m/s^2)(4s) = 260.8 m/s

Answer 2

v(4 seconds)= 300 m/s - 9.8 (m/s^2)(4s) = 260.8 m/s , hope this helps:)
