A 1000kg caristiaveling 14m's to the right when it collides head-on with a 2000kg pickup truck traveling Sinus to the left the vehicles ack together inelastically following tlie collision Which direction will the verla es travel after the collision​

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)

Iam pretty sure the answer is friction
