Question

Which would require a greater force-
accelerating a 2 kg mass of 5 ms' or a 4 kg
mass of 2 ms​

Answer 1

Answer:

it will be 1

Step-by-step explanation:

FORCE= mass x acceleration. 2 x 5 = 10 N. 2. FORCE=mass x acceleration. 4 x 2 = 8 N.

Answer 2

$\huge\underline\mathrm{Question}$

Which would require a greater force-accelerating a 2 kg mass of 5 ms' or a 4 kg mass of 2 ms?

$\huge\underline\mathrm{AnSweR}$

Here we have,

$\sf\:m _{1} = 2kg \: a_{1} = 5 \: m \: s^{ - 2}$

$\sf\:and \: m_{2} = 4 \: kg \: a_{2} = 2 \: m \: s^{ - 2}.$

$\sf\:thus \: f_{1} = m_{1}a_{1} = 2 \: kg \times 5 \: m \: s^{ - 2} = 10n$

$\sf\:and \: f_{2} = m_{2}a_{2} = 4 \: kg \times 2 \: m \: s^{ - 2} = 8n$

$\sf\:f_{1} > f_{2}$

Thus, accelerating a 2 kg mass at 5 m s-² would require a greater force..
