The car leaves the ramp at a velocity of 60 m/s at an angle of 45 o to the horizontal; the cliff and ramp combined cause the car to begin its projectile motion at a height of 315m above the ground. If a projectile is launched from height H, the angle for maximum range to a target at zero height is less than 45°. Neglect air friction. 84 - 3/5/2020. It reaches its maximum height in 3. The angle at which the projectile is launched affects the distance that it travels. If a second projectile is launched with the same initial velocity but at an angle of 60 degree above the horizontal, A) the range of the second projectile will be twice that of the first. Projectile Motion CHECK YOUR ANSWER Neglecting air drag, a ball tossed at an angle of 30 ° with the horizontal will go as far downrange as one that is tossed at the same speed at an angle of A. Don’t change the velocity or mass, only change the angle. Note that the projection speed steadily decreases as the athlete tries to throw with a higher and higher projection angle. the minimum radius of curvature of trajectory described by the projectile is A. Optimal angle for a projectile part 1: Components of initial velocity. Predictable unknowns include the time of flight, the horizontal range, and the height of the. Range is 0.
