Last time now, with d = 4.02 m. You start the block on the track at rest, somewhere to the left of x = 0. You then release the block from rest and let it slide down. What is the maximum value of x (that is, what is the closest to the origin) from which you can release the block from rest and have it leave the track at x = 0 and go into freefall?

-1.66 m

-2.01 m

-1.42 m

-2.74 m

. Block A and Block B start from rest on a horizontal track. An ideal string pulls cart A with a constant force of 25 N, causing both of the carts to move together as they accelerate. The coefficient of kinetic friction between the blocks and the track is 0.10. Block A= 4.0kg and Block B= 1.0kg (pulled horizontally) Determine the magnitude of each individual force that acts on Block A and each individual force that acts on Block B.

You buy an island and start a country! Now it is time to establish a tax. Explain ONE consideration not ALREADY mentioned by your classmates that must be considered when establishing a tax. Do not consider how much you'll spend or on what- only how you'll collect tax money. I have about 10 things to consider when designing a tax, so if we run out of ideas then you may use an idea a second time so long as you...

A block of mass m is pressed against a light spring by a distance d and...

A block of mass m is pressed against a light spring by a distance d and is kept at rest (Fig. 1). The spring, of elastic constant k, is released and the block is thrown on a horizontal surface without friction. The smooth surface curves upward and the block rises. Calculate your speed when you have climbed a height h. (Express v as a function of k, m, d, h and g).

Suppos you have a block resting on a horizontal smooth surface. The block (with mass m)...

Suppos you have a block resting on a horizontal smooth surface. The block (with mass m) is attached to a horizontal spring (spring constant k), which is fixed at one end. The spring can be compressed and stretched. The mass is pulled to one side and released. The maximum displacement is 15cm. a) If k=150N/m, calculate the mass of the block. b) Draw the graphs for velocity and acceleration of the motion. On the graphs, label the maximum values of...
