Kindly check explanation
Explanation:
Given the following :
Initial Velocity (u) = 10m/s
Angle (θ) = 50°
Horizontal length d1 = 6m
Height d2 = 3.6m
g = acceleration due to gravity = 9.8m/s²
Horizontal component :
X = U× cosΘ = 10 × cos 50 = 10 × 0.6429 = 6.43t
X = 6.43t
Vertical component :
Y = Usinθ - 1/2gt² = 10 ×sin 50 - 1/2(9.8)t² = 7.66t - 4.9t²
From X :
t = X / 6.43
Hence,
Y = 7.66(X/6.43) - 4.9(X/6.43)²
Y = 1.19X - 0.12X²
Slope of ramp Y':
(3.6 ÷ 6)X = 0.6X
Hence,
Y = Y'
1.19X - 0.12X² = 0.6X
-0.12X² = 0.6X - 1.19X
-0.12X² = - 0.59X
X² / X = 0.59 / 0.12
X = 4.92 m
Ball hits the ramp as X is < 6m
