kinetic energy is converted into elastic potential energy stored in the brakes.
the higher concentration of molecules, the faster a reaction can occur
Answer:
(C) greater than zero but less than 45° above the horizontal
Explanation:
The range of a projectile is given by R = v²sin2θ/g.
For maximum range, sin2θ = 1 ⇒ 2θ = sin⁻¹(1) = 90°
2θ = 90°
θ = 90°/2 = 45°
So the maximum horizontal distance R is in the range 0 < θ < 45°, if θ is the angle above the horizontal.
Correct option is=A
because 25mph means=25miles per hour
