acceleration=force divide by mass . How do you solve 20m/s2 =unknown divide by 0.15kg

a = F/m,

Multiply both sides by m:
F = ma = 0.15 * 20 = 3 N.

OR
a = F/m,
20 = F/0.15,
Solve for F:
F = 0.15*20 = 3 N.

To solve the equation 20m/s^2 = unknown / 0.15kg, you need to isolate the unknown variable. In this case, the unknown variable is the force (F).

To isolate the force (F), you can rearrange the equation using algebraic manipulation. Multiplying both sides of the equation by 0.15kg, we can cancel out the units on the right-hand side:

20m/s^2 * 0.15kg = unknown

Now, simply multiply the values:

3N = unknown

So, the unknown force is equal to 3 Newtons (N).
