Academics

Q. A bullet is fired vertically into a 1.50 kg block of wood at rest directly above it. If the bullet has a mass of 29 g and a speed of 570 m/s, how high would the block rise after the bullet becomes embedded in it?

Q. A charge of -3.65 nC and a charge of -6.70 nC are divorced by a distance of 70.0 cm. Find the position at which a third charge of +7.30 nC can be placed so that the net electrostatic force on it is zero.
