A ball is dropped vertically from heigth h\mathrm{h} and is bouncing elastically on the floor (see figure). Which of the following plots best depicts the acceleration of the ball as a function of time. A ball is dropped vertically from heigth h and is bouncing elastically on the floor (see figure). Which of the

Options

  1. ALet A and B be matrices of order 3 × 3 . If |A|= 1 2 2 and |B|=(1)/(729) , then what is the value of 2 B(adj(3 A) ?
  2. BLet A and B be matrices of order 3 × 3 . If |A|= 1 2 2 and |B|=(1)/(729) , then what is the value of 2 B(adj(3 A) ?
  3. CLet A and B be matrices of order 3 × 3 . If |A|= 1 2 2 and |B|=(1)/(729) , then what is the value of 2 B(adj(3 A) ?
  4. DLet A and B be matrices of order 3 × 3 . If |A|= 1 2 2 and |B|=(1)/(729) , then what is the value of 2 B(adj(3 A) ?

Correct answer

B. Let A and B be matrices of order 3 × 3 . If |A|= 1 2 2 and |B|=(1)/(729) , then what is the value of 2 B(adj(3 A) ?

Step-by-step solution

Acceleration is all the time (−g)(-\mathrm{g}) except at the time of collision it is impulsive force in (+)ve decrease.
