which would requires a greater force accelerating a 4kg mass at 10m/s^2 or 10 kg mass at 2m/s^2 ​

Answer 1

Answer:

Reporting a robotext or spam message to your cellular carrier is a great step to take in the fight against robotexts and spam messages. Copy and forward the original text to 7726 (SPAM), free of charge. You can use this method if you are a Verizon, AT&T, T-Mobile, Sprint, or Bell subscriber.

Answer 2

$\huge\mathfrak\green{Answer} \:$

The formula for force when mass and acceleration are given is Force (F)= Mass (M)* Acceleration(A).

So the force required for accelerating 2kg mass at 5ms2 is

Force (F)= Mass (M)* Acceleration(A)

= 2*5

= 10N

The force required for accelerating 4kg mass at 2ms2 is

Force (F)= Mass (M)* Acceleration(A)

= 4*2

= 8N

So the force required for 2kg mass at 5ms2 is more than the force required for accelerating 4kg mass at 2ms2
