We know, Impulse of a body is change in momentum.
Also, the final velocity of wood block is 0 m/s.
So, Impulse = Final Momentum - Initial Momentum
Impulse = 0 - ( 0.05 kg × 350 m/s )
Impulse = - 17.5 kg m/s
Therefore, the impulse exerted by the wood on the bullet is -17.5 kg m/s .
Higher the pressure the air would spread apart causing the paper to move to the other side. So higher pressure causes the papers to move farther apart.
The correct answer among the choices provided is option C. The magnitude of the sum of 20 and 25 might be 12. Inequality triangle equation is used to determine if 12 is right.
<span>12+20 > 25 (correct)
12+25 > 20 (correct)
20+25 > 12 (correct)</span>
Presuming that air resistance can be ignored and we are saying that it accelerates due to gravity then we can form an equation using the formula s=ut+1/2at²
u=0
t=10
a=9.8
s=0*10+1/2*9.8*10²
s=490m
