Question

Which would require a greater force, accelerating a 3kg
mass at 5 m/s2 or a 5 kg at 4 m/s2 ?

Answer 1

Answer:

we know F=ma where m= mass and a= acceleration

F1=m1 a1

= 3* 5=15 N

F2= m2 a2

= 5*4 = 20 N

hence second case requires a greater force

Answer 2

Answer:

m=5kg & v= 4 m/s require a greater force.

hope this hlp u!!

Explanation:

F1 = m ×a

= 3×5 ➜ 15 N

F2= m×a

=5×4➜20 N

F2 require a great force.
