A0.4 kg piece of ice at -20 ∘c is dropped from a height h. upon impact, 6.0 % of its kinetic energy is converted into heat energy.

if the impact transforms all of the ice into water that has a final temperature of 0 ∘c, find h.

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

Asmall grinding wheel has a moment of inertia of 4.0×10−5 kg⋅m2 . what net torque must be applied to the wheel for its angular acceleration to be 150 rad/s2 ?
