Ameteoroid is moving towards a planet. it has mass m = 0.78×109 kg and speed v1 = 4.1×107 m/s at distance r1 = 2.8×107 m from the center of the planet. the radius of the planet is r = 0.26×107 m. the mass of the planet is m = 4.4×1025 kg. there is no air around the planet. calculate the value of pe1, in joules

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
