Question

a pendulum , swinging back and forth , rises at the end of its swing to a position 15 cm higher than its lowest point. how fast is it going at the lowest point.​

Answer 1

Answer:

1.714m/s

Explanation:

As Intial velocity will be 0 bcuz it will reach its highest point so there it's velocity will be zero

Now,V²=u²+2gh Put values u=0,g=10m/s,h=15/100 or 0.15 metres

answer will be √3 = 1.714m/s
