The initial kinetic energy imparted to a 0.020 kg bullet is 1200 j. (a) assuming it
accelerated down a 1.00 m rifle barrel, estimate the average power delivered to it during
the firing. (b) neglecting air resistance, find the range of this projectile when it is fired
at an angle such that the range equals the maximum height attained.

(a) Power= 207.97 kW

(b) Range= 5768.6 meter

Explanation:

Given,

Mass of bullet,

Kinetic energy imparted,

Length of rifle barrel,

(a)

Let the speed of bullet when it leaves the barrel is .

Kinetic energy,

Initial speed of bullet,

The average speed in the barrel,

Time taken by bullet to cross the barrel,

Power,

(b)

In projectile motion,

Maximum height,

Range,

given that,

then,

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

think its the third option
