Question

A pair of toy freight cars, one twice the mass of the other, fly apart when a compressed spring that joins them is released. Acceleration will be greater for the:

Answer 1

greater acceleration is experienced by the car with lower mass

Step-by-step explanation:

Since both the toys are connected by same spring so the force due to spring on both the toys will be same and it is given as

`F = kx`

now we know by Newton's II law

`F = ma`

so here we have

`a = (F)/(m)`

here we have same force on both the blocks

so acceleration will be more if mass is less

so greater acceleration is experienced by the car with lower mass
