What is the current in a 45 kΩ resistor with 150 Vacross it?

A 14 kg projectile is launched at 380 m/s at a 55 ∘ angle to the horizontal. At the peak of its trajectory it collides with a second projectile moving horizontally, in the opposite direction, at 140 m/s . The two stick together and land 9.3 km horizontally downrange from the first projectile's launch point.?

A projectile is launched at a speed of 39.1m/s and an angle of 25˚ above the horizontal surface so that it lands on a target 120 m away. Neglect air resistance. The projectile is in the air for 3.4s. Someone constructs a wall between the launch site and the target that is just high enough to block the projectile's path. If the launch speed cannot be changed, at what angle could we launch the projectile to ensure that it still...

A 4.0 kg projectile is launched into the air with an initial velocity of 15 m/s at an angle of 30° above the horizontal. When the projectile reaches its maximum height it explodes, splitting in two parts, one of mass 3.0 kg and one of mass 1.0 kg. Assume the explosion was essentially instantaneous. Determine the maximum height of the projectile using energy. After the explosion, if the 1.0 kg mass is moving at 1/2 the speed it was right...

A streamlined and compact projectile is launched from flat ground on a valley toward a distant hillside at an Army testing ground in Nevada. The projectile’s initial speed is vi = 150. m/s as it leaves the cannon. The initial angle of launch θi of the projectile is unknown. The projectile makes impact high on the distant hill a time t = 3.00 s after its departure. From GPS sensors we know that the site of impact is a straight-line...
