hey everyone, i have a few questions that i just don't understand.(adsbygoogle = window.adsbygoogle || []).push({});

1) a golfer imparts a speed of 27.0m/s to a ball, it travels the max possible distance b4 landing on the green. the tee and the green are at the same level. a) how much time does the ball spend in the air? b) wat is the longest "hole in one" that the golfer can make, if the ball does not roll when it hits the ground?

2)suppose the water at the top of niagara falls has a horizontal speed of 1.51m/s just b4 it cascades over the edge of the falls. at wat vertical distance below the edge does the velocity vector of the water point downward at a 37.2 degree angle below the horizontal?

3)the mass of a robot is 4230kg. the robot weighs 3220N more on planet A than it does on planet B. Both planets have the same radius of 3.64e6m. wat is the difference mA-mB in the masses of these planets?

4)the large blade of a helicopter is rotating in a horizontal circle. the length of the blade is 6.82m, measured from its tip to the center of the circle. find the ratio of the centripetal acceleration at the end of the blade to that which exists at a point located 2.80m from the center of the circle.

5)a car can negotiate an unbanked curve safely at a certain max speed when the coefficient of static friction between the tires and the ground is 0.530. at wat angle should the same curve be banked for the car to negotiate the curve safely at the same max speed w/o relying on friction?

6)a satellite has a mass of 4120kg and is in a circular orbit 2.66e5m above the surface of a planet. the period of the orbit is 1.98hrs. the radius of the planet is 9.97e6m. wat is the true weight of the satellite when it is at rest on the planet's surface?

i would really really appreciate ur help and if someone can do these problems can u please give clear solutions?

thanx alot
