Question

Which would require a greater force - accelerating a 1 kg mass at 10 m/s2or a 2 kg mass at 4m/s2?

Answer 1

By second law of motion we have the formula as :-
Force = mass × acceleration

Given Force 1 = 1 × 10 = 10 Newton


Given Force 2 = 2 × 4 = 8 Newton


Hence, force 1 is greater than force 2.

SI unit of force is Newton. 1 kg = nearly 9.8 N

Hope it helps dear friend ☺️✌️

Answer 2

f = ma so u can find the force in two cases. case1) f=1×10= 10N . and in case2) f=2×4= 8N since case 1 has greater force. THANKYOU
