The Force on a bullet is given by the formula F = 580 – (1.8 x 10)t over the time interval t = 0 to t = 3.0 x 10-3s. In this formula, t is in seconds and F is in newtons.
(a) Plot a graph of F vs f for t = 0 to t = 3.0m.s
(b) Estimate, using graphical methods, the impulse given the bullet.
(c) If the bullet achieves a speed of 220 m/s as a result of this impulse, given to it in the barrel of a gun, what must its mass be? |
