Answer:
B.150 N
Step-by-Step Explanation:
To find the amount of force we applied, we will use Newtons Law of Motion. The formula that is mainly used to solve for force is: [tex]F=ma[/tex].
[tex]F = 30kg * 5m/s^{2}[/tex]
Now we just simply multiply the two values to find N.
F = 150 N.
Answer:
The correct answer is option B.
Explanation:
Force of an object is defined as product mass and acceleration by object is moving.
Force=[tex]mass\times acceleratio[/tex]
Given mass of the cart= 30kg
Acceleration by which cart is pushed = [tex]5m/s^2[/tex]
Putting in the values we get,
Force =[tex]30 kg\times 5 m/s^2=150 kgms^{-2}=150 N[/tex]
[tex]1kgms^{-2}=1Newton(N)[/tex]
Hence, the correct answer is option B.
