Force exerted by the bullet = mass * acceleration = 0.013 * 850 = 11.05 Newtons.
the rifle exerts same force in opposite direction so we have
11.05 = 3.5 * a
acceleration = 11.05 / 3.5 = 3.16 m /s^-2
Wood isn’t a medium. Pls give brainliest
A) the final velocity = 66/9 m/s.
b) The total momentum before and after collision is the same because energy is destroyed or made.
Thanks brainly. <span />
Answer:
8m/s
Explanation:
Average Speed = distance / time = 400/50 = 8m/s
It is 6 g/cm3 because density cannot be negative, and it is not speed in which the unit would be m/s.
