Can anyone help with these 2?
1.) An object of mass 7.0 kg is dropped from a certain height. Just before it strikes the ground it has a kinetic energy of 1750 J. From what height was the object dropped? Ignore air resistance.
2.) A 2.0g bullet hits and becomes embedded in a 5.0kg wood block which is hanging from a 1.4 m long string. This causes the block to swing through an arc of 4.5 (Degrees). What was the speed of the bullet before it hit the block ?
