The answer might be because of kinetic energy is still there and it got transferred, but it's hard to tell, I'd need more info:/
Answer:
Option A
Explanation:
Ast the force is equal and the diayance is equal the beam is also balanced
Kinetic energy is the energy possessed by a body in motion while potential energy is the energy of a body at rest.
Kinetic energy is given by E=1/2MV² where M is the mass of the body while V is the velocity of the body.
To get mass we can use the formula M= 2 Ek/V² (Making M the subject)
hence mass = (2 ×675)÷35²
= 1.102 kg
