Agolfer tees off from the top of a rise, giving the golf ball an initial velocity of 44 m/s at an angle of 25° above the horizontal. the ball strikes the fairway a horizontal distance of 190 m from the tee. assume the fairway is level. (a) how high is the rise above the fairway? (b) what is the speed of the ball as it strikes the fairway?

a)

b)

Explanation:

From the exercise we got our initial data

a) To find maximum height we know that at that point

Solving for y

b) Since we know that the ball strikes the fairway 190 m away

Solving for t

Now, we can calculate the speed of the ball in both axes

The negative sign means the direction of the ball at that point.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
