<h2>
Speed of the race car at the end of the run is 97.57 m/s</h2>
Explanation:
We have equation of motion v² = u² + 2as
Initial velocity, u = 0 m/s
Acceleration, a = 11.9 m/s²
Final velocity, v = ?
Displacement,s = 400 m
Substituting
v² = u² + 2as
v² = 0² + 2 x 11.9 x 400
v = 97.57 m /s
Speed of the race car at the end of the run is 97.57 m/s
Surface tension, the curve is called the meniscus
Answer:
R = V^2 sin 2 θ / g range formula
R is a maximum for θ = 45 and R = V^2 g
g = V^2 / R = 3^2 / 15 = .6 m/s^2
