Achild in a boat throws a 5.80-kg package out horizontally with a speed of 10.0 m/s. the mass of the child is 24.6kg and the mass of the boat is 39.0kg . (figure 1)

calculate the velocity of the boat immediately after, assuming it was initially at rest.

express your answer to three significant figures and include the appropriate units. enter positive value if the direction of the force is in the direction of the velocity of the box and negative value if the direction of the force is in the direction opposite to the velocity of the box.

Work = force × a. work b. energy c. distance d. momentum

Need only answer if you think you know it

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
