A and B are summits of two mountains that rise from a horizontal plain. B being 2200 meters above the plain. Find the height of A, it being given that its angle of elevation as seen from a point C in the plain ( in the same vertical plane with A and B ) is 60 degrees, while the angle of depression of C viewed from B is 38 degrees 58 minutes and the angle subtended at B by AC is 50 degrees. Write the numerical value only, 3 decimal places

Two blocks connected by a light string are being pulled across a frictionless horizontal tabletop by a hanging 15.0-N weight (block C). Block A has a mass of 4.00 kg. The mass of block B is only 1.00 kg. The blocks gain speed as they move toward the right, and the strings remain taut at all times. ? 1) Assuming the pulley is massless and frictionless, what is the value of the tension T1? (Express your answer to three significant...

. Block A and Block B start from rest on a horizontal track. An ideal string pulls cart A with a constant force of 25 N, causing both of the carts to move together as they accelerate. The coefficient of kinetic friction between the blocks and the track is 0.10. Block A= 4.0kg and Block B= 1.0kg (pulled horizontally) Determine the magnitude of each individual force that acts on Block A and each individual force that acts on Block B.
