How do you calculate principal when given rate and time?
Principal Amount Formulas
We can rearrange the interest formula, I = PRT to calculate the principal amount. The new, rearranged formula would be P = I / (RT), which is principal amount equals interest divided by interest rate times the amount of time.
How do you find rate and time in simple interest?

| d | Distance |
| t | Time |
What is the formula of time and work?

How do you find time in projectile motion?
To define the time of flight equation, we should split the formulas into two cases:
- Launching projectile from the ground (initial height = 0)
- t = 2 * V₀ * sin(α) / g.
- Launching projectile from some height (so initial height > 0)
- t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.
How do you solve time and work problems?
