Question

wha force is needed to accelerate a 40-kg block of concrete at 5 m/s/s?

Answer 1

Answer:

200N

Explanation:

F=m×a

=40×5

F =200 Newton

Answer 2

Given

Mass = 40 kg

Acceleration = 5 m/s²

To Find

Force

Solution

We know that

$\rm \longrightarrow F=ma$

Here

• F = Force
• m = Mass
• a = Acceleration

Units

• F = Newton (N)
• m = kg
• a = m/s²

According to the question

We are asked to find force

Therefore

We must find "F"

Given that

Mass = 40 kg

Acceleration = 5 m/s²

Hence

• m = 40 kg
• a = 5 m/s²

Substituting the values

We get

$\rm \longrightarrow F=40 \times 5 \ N$

Therefore

$\rm \longrightarrow F=200 \ N$

Hence

Force = 200 N
