Shooting down planes from the ground during WWII was difficult. A timed explosive is used because hitting a moving aircraft with a single shot from a cannon is nearly impossible; This explosive allows you to be less accurate. You are responsible for aiming and setting the timed fuses for anti aircraft battery (cannon). You fire a projectile that is aerodynamic enough that you can ignore air resistance. The projectile leaves the barrel at 840m/s. Your target is at an altitude of 3000m and a horizontal distance of 4000m.

1.Find the flight time in algebraic expression.

2. At what angle above horizontal must you aim?

3.What does the delay need to be on the fuse?

. During droughts, water for irrigation is pumped from the ground. When ground water is pumped excessively, the water table lowers. In California, lowering water tables have been linked to reduced water quality and sinkholes. A particular well in California’s Inland Empire has been monitored over many years. In 1994, the water level was 250 feet below the land surface. In 2000, the water level was 261 feet below the surface. In 2006, the water level was 268 feet below...

A request has been received from an external customer for recommendations for linear position control sensors to be used in an explosive environment.

A request has been received from an external customer for recommendations for linear position control sensors to be used in an explosive environment. For this reason unsafe electrical contacts must be avoided. The sensors will be installed in locations that are hazardous to access except when the plant is shut down annually for maintenance. The span required is 5 cm. The sensor case must not permit any ingress of dust or of water. State what type of position sensors...
