Abullet of 10g strikes a sand bag at a speed of 100 m/s and gets embedded after travelling
5 cm inside the bag. calculate the resistive force exerted by the sand on the bullet and the time
taken by the bullet to come to rest. with calculation

-1000 N

Explanation:

First calculate the acceleration:

v² = v₀² + 2a(x - x₀)

(0 m/s)² = (100 m/s)² + 2a (0.05 m)

a = -100,000 m/s²

Now calculate the force:

F = ma

F = (0.010 kg) (-100,000 m/s²)

F = -1000 N

answer: electrons

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
