Question

which would require a greater force accelerating a 2 kg mass at 5 metre per second or a 4 kg mass at 2 metre per second​

Answer 1

Answer:-

1.

FORCE= mass x acceleration

2 x 5 = 10 N

2.

FORCE=mass x acceleration

4 x 2 = 8 N

force of (1) is more

so (1)will require a greater force.

Answer 2

Answer:

we have f =ma

here we have mass 1 is 2 kg acceleration one is 5 metre per second... mass 2 is 4 kg acceleration 2 is 2 metre per second....

F1>F2

THUS ACCELERATING A 2 KG MASS AT 5 METRE PER SECOND WOULD REQUIRE A GREATER FORCE....
