A 1.25-kg wooden block rests on a table over a large hole shown. A
5.00-9 bullet with an initial velocity
v is fired upward into the bottom of
the block and remains in the block
after the collision. The block and
bullet rise to a maximum height of
22.0 cm. Calculate the initial
velocity of the bullet. [in m/s]. use
the correct number of significant
figures based on the data provided.​

The answer should be a.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !

There was no intial y-momentum so the net final y-momentum must also be 0. they can have final velocities in the y-direction
