Answer:
After 14.92 seconds, the arrow hits the ground.
Step-by-step explanation:
Given:
Initial velocity of the arrow is, 
The arrow goes up and come back to the same starting position. So, initial position is same as that of final position.
Therefore, displacement of the arrow is 0 m.
The displacement of the arrow is given as:
(equation 1)
Plug all value in equation 1 and solve for 
where 
∴ After 14.92 seconds, the arrow hits the ground.
68 miles / hour
Average speed = distance / time
distance = 170 and time = 5/2 ( as an improper fraction)
speed = 170 ÷ 
= 170 × 
= 
= 68
The product will be 40 I believe?
Answer:
88°
Step-by-step explanation:
The triangle is an isosceles triangle, so two of the angles are both 46°. We also know that the sum of all the angles in any triangle is 180°, so we can set up the following equation:
46° + 46° + e = 180°
Solving this gets e = 88°.
