Answer»

\bigstar Question

Force REQUIRED in accelerating

  • 4 kg mass at 5 m/s²
  • 3 kg mass at 7 m/s²

\bigstar Solution

We know that

\red{\rm \longrightarrow F=ma}

Here

  • F = force
  • m = mass
  • a = acceleration

Units

  • F = Newton (N)
  • m = KILOGRAM (kg)
  • a = metres/second square (m/s²)

According to the question

We are asked to find force

Therefore

We must find "F"

From the GIVEN question

  • 4 kg mass at 5 m/s²

Hence

  • m = 4 kg
  • a = 5 m/s²

Substituting the values

We get

\rm \longrightarrow F_{1}=4 \times 5 \ N

Therefore

\rm \longrightarrow F_{1}=20 \ N

Similarly

From the given question

  • 3 kg mass at 7 m/s²

Hence

  • m = 3 kg
  • a = 7 m/s²

Substituting the values

We get

\rm \longrightarrow F_{2}=3 \times 7 \ N

Therefore

\rm \longrightarrow F_{2}=21 \ N

Hence

Required forces are

\rm \longrightarrow F_{1}=20 \ N

\rm \longrightarrow F_{2}=21 \ N
