Answer:
KE = 1/2mv^2
KE = 1/2(1120)(40^2)
KE = 560(1600)
KE = 896000

Answer: echo
Explanation:radar, microwave radar, radio detection and ranging, radiolocation(noun) measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects. Synonyms: radiolocation, microwave radar, radio detection and ranging.
The segment of the motion that net force act on the object causing a positive acceleration is segment 1.
<h3>
Motion of an object</h3>
The motion of an object occurs when a net force greater than zero acts on the object.
The force on the object is determined from Newton's second law of motion.
F(net) = ma
where;
- m is mass of the object
- a is acceleration of the object
<h3>Acceleration of the object from the graph</h3>
- Segment 1: the acceleration is positive
- Segment 2: the acceleration is zero
- Segment 3: the acceleration is negative
- Segment 4: the acceleration is zero
Thus, the segment of the motion that net force act on the object causing a positive acceleration is segment 1.

Answer:
The dog ran a total distance of 45m but he is only 5m away from the starting line
Explanation: When you add 25 to 20 you get 45 for the total distance and if he ran back in the same direction then you would subtract 20 from 25 and get 5m
