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

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

A40.0 l tank of ammonia has a pressure of 12.7 kpa. calculate the. volume of the ammonia if it’s pressure is changed to 8.4 kpa while its temperature remains constant.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
