A system is setup to launch an object horizontally off desks with an initial speed of 4.2 m/s. Height of desk is 1.3 meters.
What time of flight should be predicted for the object?
Δt = (v2 - v1) / ∂ (Not too sure)
The Attempt at a Solution
1.3/4.2 = 0.31 seconds
Hello. I tried to find the time, but I keep getting the time wrong. The actual answer is 0.52s, but I think I'm going the wrong way about it :( Can someone help me understand the question more and lead me into the right direction? I'm not very good at physics.
