Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. Suppose a spitting cobra rears up to a height of 0.520 m above theground and launches venom at 2.80 m/s, directed 57.0° above the horizon. Neglecting air resistance, find the horizontal distance (in m) traveled by the venom before it hits the ground.

Solution: Projectile of the venom is shown in the figure below The venom will travel upwards…

Answered: Spitting cobras can defend themselves…

A boat is aimed at the opposite shore of a 418.51 m wide river and rowed at a speed of 7.89 m/s relative to the water. The current in the river is at a right angle to the velocity of the boat relative to the water. The current in the river is at 2.27 m/s. What is the speed of the boat relative to an observer on the shore?
Water flows as two free jets from the tee attached to the pipe shown in Fig. P5.33. The exit speed is 15 m/s. If vis- cous effects and gravity are negligible, determine the x and y components of the force that the pipe exerts on the tee. 5.33 V = 15 m/s Area = 0.3 m? Area = 1 m2 V= 15 m/s Area = 0.5 m2 `Pipe Tee ===
At max load, the elevator E weighs 8000 lb. The counterweight C weighs 3500 lb. Research shows that generally speaking, elevator speeds reach up to 600 ft/min, and are designed to accelerate at about 10 ft/s². If the elevator is at capacity, the motor has an efficiency of 85%, and the mechanical systems (pulleys, cables, etc.) experience various energy losses totaling 30%, find the required power input to the motor if... (a) The elevator is accelerating and moving up at maximum rates. (b) The elevator is moving up at a constant max rate. (c) The elevator is moving down at a constant max rate. E C M
Consider a projectile launched at a height h feet above the ground and at an angle ? with the horizontal. If the initial velocity is v0 feet per second, the path of the projectile is modeled by the parametric equations x = t(v0 cos(?)) and y = h + (v0 sin ?)t - 16t2.Let h=6, v0=63.25, and ?=0.79. Find the maximum height of the projectile. (Round your answers to two decimal places.)
