A person is standing 15.5 m from a target, which is at a height of 3.10 m. The person wishes to throw a ballso that it strikes the target. A ball is thrown with an initial velocity directed 40.0° above the horizontal. The ballis released from a point that is 1.90 m above the ground. What initial velocity is required in order for the ball tostrike the target?A baseball batter hits a long fly ball, giving it an initial velocity 45.0° above the horizontal. The ball risesto a maximum height of 14.8 m. An outfielder on the opposing team starts running at 7.60 m/s the instantthe ball is hit. Calculate the farthest the fielder can be from where the ball will land so that it is possiblefor him to catch the ball, i.e. distance between fielder’s original position and lading of the ball
- A baseball batter hits a long fly ball, giving it an initial velocity 45.0° above the horizontal. The ball risesto a maximum height of 14.8 m. An outfielder on the opposing team starts running at 7.60 m/s the instantthe ball is hit. Calculate the farthest the fielder can be from where the ball will land so that it is possiblefor him to catch the ball, i.e. distance between fielder’s original position and lading of the ball. [HINT: Assume that the outfielder catches the ball at the same height at which it was hit, and that hebegins running at the same time that it was hit.]1) A projectile is launched at 300 ?/s at an angle of 60 degrees.The projectile lands 500 m below its starting level in a valley. What is the horizontal Range for the projectile?Spitting cobras can defend themselves by squeezingmuscles around their venom glands to squirt venom atan attacker. Suppose a spitting cobra rears up to a height of0.500 m above the ground and launches venom at 3.50 m/s,directed 50.0° above the horizon. Neglecting air resistance,find the horizontal distance traveled by the venom before ithits the ground.
