An object is moving in the absence of a net force. which of the following best describes the object's motion?

the object will speed up at a constant rate until it reaches a maximum speed.
the object will continue to move with a constant velocity.
the object will slow down at a constant rate until coming to rest.
the object will stop moving immediately and remain at rest until acted on by a net force.
the object will continue to move with a constant speed, traveling in a circular path.

Explanation:

An object is moving in the absence of a net force. It means the net force acting on the object is zero. According to Newton's second law of motion, the force acting on the object is given by :

According to given condition, F = 0

Mass of the object cannot be equal to 0.

v = u

Final velocity = initial velocity

i.e. the final speed of the ball is equal to its initial speed. It means, the object will continue to move with a constant velocity. Hence, the correct option is (a).

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
