यदि एक गेंद को 3 m/s की चाल से लंबवत ऊपर की ओर फेंका जाता है, तो इसके द्वारा प्राप्त अधिकतम ऊंचाई ज्ञात कीजिए। (g = 10 m/s2 लें)

A car falls off a ledge and drops to the ground in 0.8 s. Taking g = 10 m/s2, how high is the ledge from the ground?

If a body at rest is dropped from a certain height and takes 4 seconds to reach the ground, what is the approximate height from which it was dropped? (Take g = 10 m/s2)
