Problem
A particle of mass 0.01 kg is projected with velocity 2i m/s from point x=0; y=20. After two seconds, what are its position coordinates?
Solution
First, we need to find the particle's initial velocity components:
- Initial velocity in the x-direction: Since the particle is projected with velocity 2i m/s, its initial velocity component in the x-direction is 2 m/s.
- Initial velocity in the y-direction: The particle is projected vertically upwards, so its initial velocity component in the y-direction is 0 m/s.
Next, we need to find the particle's displacement after two seconds:
- Displacement in the x-direction: The particle is moving with a constant velocity in the x-direction, so its displacement in the x-direction after two seconds is given by:
- Displacement in the y-direction: The particle is moving vertically upwards under the influence of gravity. Its displacement in the y-direction after two seconds is given by:
displacement = initial velocity x time
displacement = 2 m/s x 2 s = 4 m
displacement = initial velocity x time + 0.5 x acceleration x time^2
displacement = 0 m/s x 2 s + 0.5 x (-9.8 m/s^2) x (2 s)^2 = -19.6 m
Finally, we can find the particle's position coordinates after two seconds:
- Position in the x-direction: The particle's initial position in the x-direction is 0 m, and its displacement in the x-direction is 4 m. Therefore, its position in the x-direction after two seconds is:
- Position in the y-direction: The particle's initial position in the y-direction is 20 m, and its displacement in the y-direction is -19.6 m. Therefore, its position in the y-direction after two seconds is:
x = initial position + displacement = 0 m + 4 m = 4 m
y = initial position + displacement = 20 m - 19.6 m = 0.4 m
Therefore, the particle's position coordinates after two seconds are (4 m, 0.4 m).

For x axis
s=ut + 1/2at^2 (a=0)
s=2×2
s=4
position is 4+0=4
for y axis
s=ut + 1/2at^2 (a=-10 & u =0)
s = 1/2(-10)×4
s= -20
position is 20+(-20)= 0
cordinates are (4,0)
s=ut + 1/2at^2 (a=0)
s=2×2
s=4
position is 4+0=4
for y axis
s=ut + 1/2at^2 (a=-10 & u =0)
s = 1/2(-10)×4
s= -20
position is 20+(-20)= 0
cordinates are (4,0)
