a particle is projected horizontally at 15m/s from a height of 20m calculate the horizontal distance covered by the particle just before hitting the ground (g=10m/s*2)
Answered by Damon
20 = (1/2)10 t^2
solve for t = 2 seconds

d = 15 t =15*2 = 30 m

An object is projected with a velocity of 100m/s from the ground level at an angle tera to the vertical.if the total time of flight of the projectiles is 10s,calculate teta

Answer: 30m
Step-by-Step Help:
1. We know that an object is projected from and with a velocity of 100m/s from the ground level at an angle of tera to the vertical level/direction
2. We also know that the total time of the flight of projectiles is at 10 seconds/m
3. From there, we have the calculate using algebra, physics, and chemistry together: we have the calculate the tera.
4. Result: 30m
I hope this worked out well, and ask me for more questions if needed! :) ~ and remember physics is easy, just calculate it like a daily life basis, and solve mentally or even better --- physically.
