3. A diver running 1.8 m/s dives out horizontally from the edge of a vertical cliff and reaches the water below 3.5 s later. How high was the cliff? How far from its base did the diver hit the water?
my answer is height of cliff = 50.23 and hits 5.76m away from base

7. Suppose the space shuttle is in orbit 416 km from the Earth's surface, and circles the Earth about once every 92.8 minutes. Find the centripetal acceleration of the space shuttle in its orbit. Express your answer in terms of g, the gravitational acceleration at the Earth's surface.
my answer 0.00540gm/s^2

8. Because the Earth rotates once per day, the effective acceleration of gravity at the equator is slightly less than it would be if the Earth didn't rotate. Estimate the magnitude of this effect, given that the radius of the Earth is 6.38 106 and that, at the equator, it rotates at 464 m/s. What percentage of g is this?
my answer 0.344%

I did it, but the answer doesn't seem to make much sense. Someone good at physics please just do it for me to make sure that I'm right.

A 0.2 kg rock is projected from the edge of the top of a building with an initial velocity of 9.21 m/s at an angle 43 degrees above the horizontal. Due to gravity, the rock strikes the ground at a horizontal distance of 14 m from the base of the building.

Assume: The ground is level and that the side of the building is vertical. The acceleration of gravity is 9.8 m/s^2

The question I am given is: "A basketball star covers 2.60 m horizontally in a jump to dunk the ball (see figure). His motion through space can be modeled as that of a particle at a point called his center of mass (which we shall define in Chapter 9). His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.80 m above the floor and is at elevation 0.850 m when he touches down again."

And i need to find the time of flight, the initial horizontal/vertical velocity, and angle.

However, I am pretty clueless how to find the total time. I figured x(final)=.5at^2 So sqrt((0.95*2)/a)=time, but 0.44, the answer i get (times two, so 0.88) isn't the overall hang time. Now i'm just completely lost.
