Question

Two bullets are fired with horizontal velocities 50m/s and 100m/s from the guns at a height of 19.6 m at what time will the 2 bullets strike the ground ?

Answer 1

Answer:

Hence, both bullets hit the ground simultaneously after 2 seconds, at the same time .

Answer 2

Explanation:

given ,

initial velocity(u)= 50m/s

final velocity (v)=100m/s

distance (s)= 19.6m

time (t) = ?

no. of bullets = 2

solution,

(v = u +at )

100 = 50 +100-50/t *t

100 = 100 t

100/100=t

1 sec =time

time *no. of bullets = 1* 2

= 2 sec
