Distance travel = 400km
Time it took to travel 400km = 5 hr
Average speed = (distance travel)/(Time for that travel)
s = 400km/5h = 80km/hr
The average speed is 80km/hr.
We know that the formula for the centripetal force is:
F = m·v² / r
Solving for v we get:
v = √(F · r / m)
= √(36 N · 5.0 m / 20 kg)
= 3.0 m/s
The stroller moves at a speed of <span>3.0 m/s.</span>
Explanation:
the correct answer is Option C, add a cell and close the switch.
hope this helps you.
<span>Subtract the forces in the horizontal direction from the forces in the vertical direction.</span>
