Akite is flying 70 feet above the ground and is attached to a string tied to a stake on the ground. the angle of elevation formed by the string and the ground is 40°. find the length of the string to the nearest foot.
a) 45 feet
b) 83 feet
c) 91 feet
d) 109 feet

step-by-step explanation:

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
