a 200g block is pressed against a spring of force constant 1.40kN/m until the block compresses the spring 10cm. the spring rests at the bottom of a ram inclined at 60o to the horizontal. Using energy considerations, determine how far up the incline the block moes before it stops a) if there is no friction between the block ang the ramp b) if the coefficient of kinetic friction is 0.4. Compare the resuft with a) and explain/
a 2kg textbook rests on a frictionless hoorizontal surface, a cord attached to the book passes over a pulley whose diameter is 0.15m to a hanging book with mass 3kg the system is released from rest and the books are oberved to move 1.2m in 0.8s a) what is the tension in each part of the cord b)what is the moment of inertia of the pulley about its rotation axis/
