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

idk

step-by-step explanation:

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
