The net force on the object is zero, so it has no acceleration. It moves in a straight line and at a constant speed (which may be zero).
Acceleration is the change of velocity, and velocity is the change of distance. The opposite of finding change, or differentiation, is integration.
Acceleration = 1.3 m/s²
Velocity: ∫ 1.3 dx = 1.3x + c m/s
Distance: ∫ 1.3x dx = 1.3x²/2 + c m
Distance run: 1.3*3²/2 = 5.85 m

Answer:
The heavier one will have twice the kinetic energy of the lighter one.
Explanation:
For the objects of mass m and 2 m , kinetic energy is
0.5 m v² and 0.5 (2 m) v² respectively. So kinetic energy of the mass 2 m is Twice that of the object of mass m, since their final velocities are equal.
When an object is dropped from the top of a building ( or from some height), its acceleration is equal to the acceleration due to gravity and has a zero initial velocity. On reaching the ground, the final velocity attained by the object depends only on the gravity and the height of fall, as given by the equation v = √2 g h.
So final velocity is independent of the mass of the object. But kinetic energy is 0.5 m v² , which shows that it depends on the mass of the object and square of the velocity.
The answer is Phenotype.
Phenotype is the observable traits on the organism which are mainly influenced by how the genotype of the organism interacts with the environment. An example of how phenotype is determined is when a gene has several alleles. The dominant alleles are expressed in phenotype while the recessive one is masked. Epistasis of alleles also occurs in many other cases.
