Projectile motion calculator is very useful tool for evaluating motion of a thrown object making a curve in the air. This tool uses Projectile motion rules and formulas. One need to substitute the values only and it helps in finding the result will automatically come out.This can be understood and easily evaluated by the following given below examples:-

Example 1:-

Find the projectile range for a ball thrown at 20m/s and at 30 degree angle.

Solution 1:-

We can find projectile range from both speed and angle at which the ball is thrown. To find the maximum

range we use the formula

d = (V2/g) = 202/9.8 = 40.82 m

Since the angle given is 30 degrees, the projectile range will be

d = (V2 sin(2θ))/g

d = (20 x 20 sin (2x30))/9.8 = 400sin60/9.8 = 20.41 m

Example 2:-

Find the angle at which a ball is thrown with a speed of 20m/s and its projectile range is 30m.

Solution 2:-

To find that to find the angle at which the ball is thrown we have to use the projectile range formula

d = (V2 sin(2θ))/g

30 = (20 x 20 sin (2θ))/9.8 = 30x9.8/400

Sin(2θ) = 0.735

2θ = sin-1(0.735) = 47.33

180 - 47.33 = 132.67°

Answer : θ = 66.3°
