A wooden ballistic pendulum, with a mass equal to 10 kg, suspended by a wire 1 meter long, is hit at t=0 s by a 10 gram bullet, traveling at a speed of 300 m/s, which becomes stuck in it (Use g=9.8m/s2). With respect to the question, consider the following statements. I) The expression that allows to calculate the angle \theta (in rad) between the wire and the vertical as a function of time is \theta(t)=0.096 \sin(3.13\; t). II) The first instant of time in which the pendulum reaches its maximum height is t=1s. III) The maximum angular acceleration is approximately 0.94 rad/s2. It is correct what is stated in Choose an option: I, II and III. I, just. I and II only. II and III only.
