if you add them all together then divide thats u answer !
Answer: 1.4 m/s
Explanation: the acceleration equation is a = change in velocity/change in time.
Plug the values in and you get 5.6/4
Divide and get 1.4 m/s
Answer:

Step-by-step explanation:
Given: 
To find: angle to the nearest degree
Solution:
A triangle is a polygon that has three sides, three angles ,and three vertices.
Trigonometry explains the relationship between the sides and angles of the triangle.
The angle can be expressed in two forms: degrees or radians.

Given that triangle ABC is right angle triangle. CD is altitude such that AD=BC
ABC is a right angle triangle so apply Pythogorean theorem

(Given that AD = BC)
(Given that AB=3)
...(i)
ADC is a right angle triangle so apply Pythogorean theorem



...(ii)
Plug value (ii) into (i)





Hence final answer is
