Question

which would require a greater force accelerating 2kg mass at 5m/s² or 4kg mass at 2m/s² why​

Answer 1

Answer:

Object 1 requires a greater force of 2 Newtons

Explanation:

Given :

• Mass of the first object M1 = 2 kg

• Acceleration of the first object = A1 = 5 m/s²

• Mass of the second object M2 = 4 kg

• Acceleration of the second object = A2 = 2 m/s²

To find :

• Which would require a greater force to be moved

Force1 = Mass1×Acceleration1

Force for 1st object = 2×5

Force for 1st object = 10 Newtons

Force2 = Mass2×Acceleration2

Force for 2nd object = 4×2

Force for 2nd object = 8 Newtons

The force required for 1 St object is greater than the second object by 2 Newtons

Which would require a greater force accelerating 2kg mass at 5m/s² or 4kg mass at 2m/s² .. Why ?

_______________

${ \huge{ \bold{ \underline{ \underline{ \green{Answer:-}}}}}}$

★ For First Object ★

• Mass(m) = 2kg
• Acceleration(a) = 5m/s²

✒Formula Used : -

$\leadsto\sf{{ \small{ \bold{ \bold{ \bold{ \red{Force=Mass\times{Acceleration}}}}}}}}$

✒On Substituting Values : -

$\dashrightarrow\sf{2\times{5}}$

$\dashrightarrow\sf\bold{10\:N}$

★ For Second Object ★

• Mass(m) = 4
• Acceleration(a) = 2

✒Formula Used : -

$\leadsto\sf{{ \small{ \bold{ \bold{ \bold{ \blue{Force=Mass\times{Acceleration}}}}}}}}$

✒On Substituting Values : -

$\dashrightarrow\sf{4\times{2}}$

$\dashrightarrow\sf\bold{8\:N}$

→ Therefore , the force required for the first object is greater than the second object by 2 N. ..
