Question

Which would require a greater force accelerating a 6kg massage 12m/s^2 or a14kgmass at 28m/s^2

Answer 1

Case-1

• Mass=6Kg
• Acceleration=12m/s^2

Using newtons second law

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \sf\longmapsto Force=6\times 12$

$\\ \sf\longmapsto Force=72N$

Case:-2

• Mass=14kg
• Acceleration=28m/s^2

$\\ \sf\longmapsto Force=Mass\times Acceleration$

$\\ \sf\longmapsto Force=28\times 14$

$\\ \sf\longmapsto Force=392N$

CASE-2 WILL REQUIRE MORE FORCE
