A 1.5-kg cannon is mounted on top of a 2.0-kg cart and loaded with a 60-gram ball. The cannon, cart, and ball are moving forward with a speed of 1.5 m/s. The cannon is ignited and launches the ball forward with a speed of 75 m/s. Determine the post-explosion velocity of the cannon and cart.
Post-explosion speed of the cart: ← this part

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

the answer is $42.96
