Answer:
Final velocity will be 556.8 m/sec
Explanation:
We have given the average rate of change of velocity that is
Time
Initial velocity of bullet will be zero that is u=0
Now according to first law of motion
v=u+at, here v is final velocity, u is initial velocity and t is time
So
So you need to find the resulting length between the two distances. If you look at the two vectors as components of a right triangle then you can use Pythagorean theorem to solve for the last side. it is simply
which equals 165.5
Answer:
m = 1.531kg
Explanation:
F = mg
m = F/g
m = 15/9.8 = 1.531kg (Approximately)
