3. In a science fiction story about space exploration an expedition to Mars was described. The space ship landed in a rocky valley and the astronauts promptly prepared their vehicle for a trip on the planet's surface. This special vehicle was designed with big inflated tires. On the very first steep slope the vehicle tipped over. They did have small steel balls onboard to increase traction. They thought of suspending a bunch of them beneath the vehicle to lower its center of gravity, but that would decrease the clearance and cause the weights to strike rocks and the ground more often How could it be done?

Inclined plane diagram: Also String 1 String 2 String 1 B C A The diagram above shows Carts B and C which roll without friction over an inclined plane. The plane is inclined at an angle of theta = 0 away from vertical, as shown in the diagram. Carts B and C are connected by an essentially massless string. Another massless string runs from Cart B over a massless and frictionless pulley to a hanging block, Block A.

QUESTION 4 As shown in the accompanying pictures, the Chi-Cheemaun (meaning "big canoe" in Ojibwe) is a passenger and vehicle ferry that runs between Tobermory (at the tip of the Bruce Peninsula) and South Baymouth on Manitoulin Island. ex If 140 vehicles each with an average weight (including passengers) of 18 kN are loaded onto the ferry while it is parked at the dock in Tobermory, how much farther will the ferry sink into Georgian Bay? For simplicity, you can assume that the bottom section of the ferry that is submerged in the water is essentially rectangular in shape with dimensions of 19 m in width and 111 m in length.
