A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s2, what is their final velocity aft er 3 seconds?
1 answer:
<u>Statement</u><u>:</u>
A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s².
<u>To </u><u>find </u><u>out:</u>
The person's final velocity after 3 s.
<u>Solution</u><u>:</u>
Initial velocity (u) = 3.7 m/s Acceleration (a) = 2 m/s² Time taken (t) = 3 s We know, the equation of motion, v = u + at Putting the values in the above equation, we get, v = 3.7 m/s + 2 m/s² × 3 s or, v = 3.7 m/s + 6 m/s or, v = 9.7 m/s
<u>Answer</u><u>:</u>
The final velocity is 9.7 m/s in the direction of the motion.

Answer:
2 (4x - 1) + 6 = 8x + 4 = 4(2x+1)
Step-by-step explanation:
2 (4x - 1) + 6
= (2*4x + 2*-1) + 6
= 8x - 2 + 6
= 8x + 4
= 4/(2x+1)
Answer:
y=4
Step-by-step explanation:
4y + 3 =19
4y = 16
y= 4
Multiply both sides by -3 to get rid of the negative and the fraction. X - 3 = 21 Move the constants over to isolate the variable X = 24
