AP1/U1/Vectors and Motion in Two Dimensions/ap1-kin-076

Vectors and Motion in Two Dimensions

AP Physics 1· difficulty 2/5

A projectile launched at angle θ\thetaθ from level ground has range RRR. If launch speed is doubled (same angle, same gravity), the new range is

  • A

    4R4R4R

    check_circle
  • B

    RRR

  • C

    8R8R8R

  • D

    2R2R2R

Explanation

R∝v02R \propto v_0^2R∝v02​, so doubling v0v_0v0​ → 4R4R4R.
