Given:

  • Initial velocity (u) = 100 m/s

  • Angle of projection (θ) = 37°

  • Mass ratio of projectile at highest point = 1:3

  • Final velocity of smaller projectile (v1) = 0 m/s



Calculating Initial Components:

  • Initial horizontal velocity (ux) = u cos θ = 100 cos 37° = 79.87 m/s

  • Initial vertical velocity (uy) = u sin θ = 100 sin 37° = 60.6 m/s



Calculating Time to Reach Highest Point:

  • At the highest point, the vertical velocity becomes 0.

  • Using the formula: uy = u sin θ - gt, where g = 9.8 m/s² (acceleration due to gravity)

  • t = uy/g = 60.6/9.8 = 6.18 s



Calculating Maximum Height:

  • Using the formula: h = (uy²/2g)

  • h = (60.6²)/(2x9.8) = 185.93 m



Calculating Velocities of Projectile Parts:

  • Using conservation of momentum: mu = mv1 + mv2, where mv1 and mv2 are the final velocities of the smaller and larger projectiles, respectively.

  • Let the mass of the smaller projectile be m and the mass of the larger projectile be 3m.

  • At the highest point, the velocities of both projectiles are equal and opposite.

  • So, 100m = mv1 + 3mv2 and v1 = 0.

  • Therefore, v2 = 100m/3m = 33.33 m/s



Calculating Distance Travelled by Larger Projectile:

  • Using the formula: Range = (u²sin2θ)/g

  • Range = (100²sin2(37°))/9.8 = 733.6 m

  • The distance travelled by the larger projectile is 3/4 of the total range.

  • Hence, the distance travelled by the larger projectile = (3/4) x 733.6 = 550.2 m



Therefore, the distance from the launching point to the point where the heavier piece lands is 550.2 m.

Use momentum conservation on highest point and u got velocity use projectile formulas to fund distance traveled
