What force is needed to accelerate a 10 kilogram shopping cart 3 m/s^2 (squared)?
forceinNewtons=massinKg*accelerationInm/s^2
30N
To calculate the force needed to accelerate an object, you can use Newton's second law of motion. The formula is:
Force = mass x acceleration
In this case, the mass of the shopping cart is given as 10 kilograms, and the acceleration is 3 m/s^2.
Using the formula, we can calculate the force required:
Force = 10 kg x 3 m/s^2
Multiplying these values gives us:
Force = 30 kg·m/s^2
Therefore, the force needed to accelerate the 10 kilogram shopping cart at a rate of 3 m/s^2 is 30 Newtons.
To summarize:
- Use Newton's second law of motion: Force = mass x acceleration
- Plug in the given values: Force = 10 kg x 3 m/s^2
- Multiply the values: Force = 30 kg·m/s^2
- The force required is 30 Newtons.
According to Newton's second law, which certainly applies here,
F = M a
They told you what the mass (M) and acceleration (a) are.
The answer will be in Newtons.
