Q5.10Multiple correct
The motion of a particle of mass m is given by x = 0 for t < 0 s, x( t ) = A sin4p t for 0 < t <(1/4) s (A > o), and x = 0 for t >(1/4) s. Which of the following statements is true?
- (a)The force at t = (1/8) s on the particle is –16π2 A m.
- (b)The particle is acted upon by on impulse of magnitude 4π2 A m at t = 0 s and t = (1/4) s.
- (c)The particle is not acted upon by any force.
- (d)The particle is not acted upon by a constant force. (e) There is no impulse acting on the particle.
