An archer fires an arrow from a bow. the arrow’s mass is 0.088 kg, and an average force of 110 n is exerted by the bowstring over a 0.78 m distance. calculate the velocity of the arrow just after it is released by the bowstring by two methods: a) calculate the arrow’s acceleration that is caused by the bowstring, and use the kinematic equations from the first week of class to calculate the velocity at the end of the acceleration. assume a constant acceleration that corresponds to the given average force.

Explanation:

Given that,

Mass of arrow = 0.088 kg

Force = 110 N

Distance = 0.78 m

(a). We need to calculate the acceleration

Using newton's second law

We need to calculate the velocity of the arrow

Using equation of motion

Where, a = acceleration

s = distance

Put the value in the equation

(b). We need to calculate the velocity of the arrow

Using work energy theorem

Here, initial kinetic energy is zero

So,

Put the value into the formula

Hence, This is the required solution.

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.
