Explanation:
R₁ = initial distance jumped by jumper = 7.4 m
R₂ = final distance jumped by jumper = ?
θ₁ = initial angle of jump = 45°
θ₂ = final angle of jump = 42.9°
= speed at which jumper jumps at all time
initial distance jumped is given as

final distance jumped is given as

Dividing final distance by initial distance



distance lost is given as
d = 
d = 7.4 - 7.38
d = 0.02 m
