Halp!
if a force of 26 n is exerted on two rocks, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which rock will have the greater acceleration? � (f=ma) assume the rocks are the same size and surface.

the one with a mass of .78 kg will have the greatest acceleration

they will both accelerate at the same rate

the one with a mass of .52 kg will have the greatest acceleration.

there is not enough information to determine which has greater acceleration

One with mass 0.52kg will have higher acceleration.

Explanation:

We know that

F = m x a

As we can see, for a constant value of F , for a body having more mass will have less acceleration and a body having less mass will have more acceleration ( Inversely proportional when force applied is constant).

Therefore lesser mass body will have more acceleration.

Hence, 0.52 kg body will have more acceleration.

Verification :

F = ma

For 0.52kg:

a= F / m = 26 / 0.52 = 50 m/s²

For 0.78kg:

a= F/m = 26 / 0.78 = 33.3 m/s²

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
