A projectile is fired from the edge of a cliff, with an initial speed of 185 m/s at an angle of 40.0° above the horizontal. The projectile rises and then falls into the sea next to the cliff. The height of the cliff measured from the sea level is h. The time of flight of the projectile until it hits the water is 40.0 s. Ignore air resistance. What is the height h of the cliff? What is the maximum height the projectile has reached (measured from the seal level)? What is the magnitude of the ball's velocity just before it hits the ground?
A ball is thrown vertically upward with an initial speed of 88 ft/sec from the base A of a cliff with H = 60 ft. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the magnitude of the impact velocity vg. Neglect air resistance and the small horizontal motion of the ball. Answers: h = i ft t = i sec VB = i ft/sec
A grasshopper wants to jump over a thin vertical wall with the minimal possible jumping speed.The wall is h = 30 cm high and it is at distance d = 40 cm from the grasshopper. What should be the initial speed of the grasshopper? The gravitational acceleration is g = 9.8 m/s2 .Hint: The trajectory is not symmetrical to the wall. Express the starting speed v0 of the grasshopper in terms of the initial angle of elevation α, and then find the maximum of the v0(α) function
