- Velocity of the stone, u = 20 m/s
- Angle with respect to horizontal, Ѳ = 30°
- Acceleration due to gravity, g = 10 m/s²
1.MAXIMUM HEIGHT: Option c.
H= (u²sin²Ѳ)/2g
The maximum height is 5 m.
2.TIME OF FLIGHT : option b.
T = (2u sinѲ) / g
The time of flight is 2 seconds.
3.RANGE : option b
R = (u²sin2Ѳ) / g
Range is 20√3 m.
4.MAXIMUM RANGE : option b
Range is maximum when Ѳ is 45°
R = (u²sin2Ѳ) / g
Maximum range is 40 m.
