The maximum height of a projectile can be calculated using the formula: h = (v2sin2θ)/2g, where h is the maximum height, v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity. What factors affect the maximum height of a projectile?
10. An arrow is shot from a height of 1.5 m toward a cliff of height H. It is shot with a velocity of 30 m/s at an angle of 60º above the horizontal. It lands on the top edge of the cliff 4.0 s later. (a) What is the height of the cliff? (b) What is the maximum ...

It is found that the empirical coefficient ranges from 0.455 to 0.476. Taking the average empirical constant of 0.462, the empirical formula of the initial head velocity of EFPs in water is obtained by: 𝑉1−𝑊=0.462×𝐷×𝑢,V1−W=0.462×D×u, (18) Table 7. Empirical ...
Let's assume we want to calculate the time of flight and distance traveled by a ball ⚽ thrown from the Eiffel tower with a horizontal speed only, e.g., 7 m/s. Enter the velocity. In our case, it's 7 m/s. Change the units if needed. Type in the initial height from which th...
A projectile is launched from the earth's surface at initial speed v_0 at angle \theta_0 with the horizontal. When the projectile is at its maximum height h, it has half the speed it had when it was a At the earth's surface, a p...
