The gravitational acceleration is \( g= 10 \text{ m/s}^2 \) and the air resistance is negligible.
A body initially at rest is dropped from a height of \( h = 45\text{ m}. \) If the coefficient of restitution is \( e= 0.6, \) what is the height the body reaches at the second bounce?
The gravitational acceleration is \( g= 10 \text{ m/s}^2. \)
A \(14\)-meter-long rod of mass \( 2 \text{ kg} \) with homogeneous density is standing vertically with one end on a horizontal floor. Find the gravitational potential energy of the rod.
The gravitational acceleration is \( g = 10 \text{ m/s}^2. \)
