James Bond is trying to jump from a bridge and land on the first car of a moving train that is going to pass under the bridge. The train moves at 85 km/h and the vertical height between the bridge and the top of the carriage is 15 m. if Bond gets a running start of 4.2 m/s hor...

I would assume in the same direction as the train

we haven't learned about potential energy yet? is there another way to solve this?
Physics
can you explain how you derive that equation?

A car with engine trouble slides 85 meters up along a 14 degrees ramp before coming to a stop. If the coefficient of friction between the tires and the road is 0.9, what was the velocity of the car at the bottom of the ramp? I get 32.43 meters / second is this correct?
Physics
my mistake. the weight is 150 kg not 1500, and .3 m = 30 cm

A traffic light is suspended midway across a 60 meter wide street by a cable that is attached to vertical poles on either side of the street. When the traffic light is hung in the middle the cable sags 30 cm. If the light is 1500 kg what should be the minimum tension rating fo...

I found the answer, it is 1142.86 meters. I assume that the river was flowing East. so, the angle = arctan( .8 / 1.4 ) = 29.74 degrees. then tan (29.74) = offset / 2000 m = 1142.86 m

a boat crosses a 2 km wide river by starting out at the south shore and heading directly for the north shore if the river flows at 0.8 m/s and the boat can go at 1.4 m/s in still water, where on the opposite shore will the boat land?
