He's accelerating at 3 m/s² .
That means his speed is increasing by 3 m/s every second.
At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .
He's been moving south for the whole 8 seconds.
So at the end of that time, his velocity is
24 m/s south .
Answer: Hope this helps!
Explanation:
a rock formed from particles that are deposited and lithified are sedimentary.
rocks formed from cooling and hardening magma or lava is igneous.
a rock formed when an already existing rock is subjected to extreme heat and pressure is metamorphic.
Velocidad angular = (angulo total) / (tiempo total)
Velocidad angular = (1080 grados) / (20 segundos)
Velocidad angular = (1080/20) g/s
Velocidad angular = 54 g/s
Pero 180 grados = π radianes
V.A. = (54 g/s) x (π rad / 180 g)
V.A. = (54π gr-rad / 180 seg-gr)
<em>V.A. = 0.3π rad/seg</em>
V.A. = aproximadamente 0.942 rad/seg
<h2>
Average speed of round trip is 48 mph</h2>
Explanation:
Let the distance from A to B be s.
A car travels from A to B at a speed of 40 mph then returns, using the same road, from B to A at a speed of 60 mph.
Total distance traveled = 2s
Total distance traveled = Average speed x Total time
Average speed of round trip is 48 mph
