As the stan moves 0.94 s before with an acceleration 4.12 m/s^2
so the distance moved by it
speed gained by the car is given as
now the relative speed of them is given as
relative acceleration is given as
now the distance between them is to be covered
by solving above equation we have
so it will overtake after 6.64 s
Answer:
Magnitude is 25.8 m/s and direction is
Explanation:
From the law of conservation of linear momentum
where
and
are masses of bullet and stones respectively,
and
are the initial velocities of bullet and stone respectively,
and
are the final velocities of bullet and stone respectively
Substituting 6g=0.006 Kg for mass of bullet, 0.1Kg for mass of stone, 350 m/s for initial velocity of bullet and 250 m/s as final velocity for stone but initial velocity of stone is zero
Substituting 21 for and 15 for
To find direction
Therefore, magnitude is 25.8 m/s and direction is
