The impact force calculator calculates the force when two or more objects collide. Impact forces occur whenever two or more objects collide. They are usually very large and of short duration compared to the other forces acting. The most important impact force for the sport and exercise participant is that between that person and any external object. The formula for impact force is,

F = $\frac{2mv}{t}$

Where

**m**is the mass

**v**is the velocity at impact

**t**is the time

**Step 1:**Analyze the given values and note down

**Step 2:**Using the above equation, find out the unknown value

Problems related to impact force are as follows.

### Solved Examples

**Question 1:**An object of 45 kg hits in a wall with a velocity of 25 m/s in 6 s. Calculate the impact force?

**Solution:**

Given values are,

m = 45 kg, v = 25 m/s and t = 6 s

Impact force formula is,

F = $\frac{2mv}{t}$

F = $\frac{2\times45\times25}{6}$

F = 375 N

**Question 2:**An object of 90 kg hits in a wall with a particular velocity in 15 s. The impact force is given as 1500 N, calculate its velocity?

**Solution:**

Given values are,

m = 90 kg, v = ? and t = 15 s and F = 1500 N

Impact force formula is,

F = $\frac{2mv}{t}$

So, v = $\frac{Ft}{2m}$

v = $\frac{1500\times 15}{2\times 90}$

v = 125 m/s
