From Rest, A Jeepney Accelerates Uniformly Over A Time Of 3.25 Seconds And Covers A Distance Of 15 Cm

From rest, a jeepney accelerates uniformly over a time of 3.25 seconds and covers a distance of 15 cm

 

Good Day

Problem:

From rest, a jeepney accelerates uniformly over a time of 3.25 seconds and covers a distance of 15 cm

Given Data:

Vi (initial velocity) = 0 m/s

d (distance)  =  15 cm or 0.15 m  (15 cm × 1 m/ 100 cm =  0.15 m)

t (time) = 3.25 s

a (acceleration) = ? unknown

Solution:

We can use the formula a = d ÷ 1/2(t)² since Vi = 0 m/s

a = d ÷ 1/2(t)²

  = 0.15 m ÷ 1/2 (3.25s)²

  = 0.15 m ÷ 1/2 (10.56 s²)

  =  0.15 m  ÷ 5.28 s²

 = 0.028 m/s²

Answer:

acceleration is 0.028 m/s²

What Is The Second Planetary Motion?

What is the second planetary motion?   Hello! What is the second planetary motion? Solving: It is Keplers second law on planetary motion, that is, when to perform the translational motion the planet develops different velocities along the movement, the orbits of the planets are ellipses, area formed from the union of the sun to a planet by a line at equal time intervals will form equal areas, it is noteworthy that the closer to the sun, the greater the velocity of the planet and the greater the distance from the sun, the planets velocity decreases. _____________________ I Hope this helps, greetings ...
