Acar comes to a bridge during a storm and finds the bridge washed out. the driver must get to the other side, so he decides to try leaping it with his car. the side the car is on is 19.6 m above the river, whereas the opposite side is a mere 1.4 m above the river. the river itself is a raging torrent 61.0 m wide. part a
how fast should the car be traveling just as it leaves the cliff in order to just clear the river and land safely on the opposite side?
part b
what is the speed of the car just before it lands safely on the other side?

Part a)

Part b)

Explanation:

Initial height of the car is 19.6 m

final height of the bridge is 1.4 m

now the vertical displacement of the car is given as

now the time taken by the car to travel the vertical distance is given as

Part a)

Now the speed of the car so that it will just cross the cliff

Part b)

velocity gain in y direction by the car

speed in x direction is given as

so net speed of the car is given as

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
