1/ calculate the speed liquid flows out a small hole in the bottom of a large tank containing liquid to a depth of 1.0m. Hint (use Bernoulli equation)

2/ A bullet with a mass of 15 grams is fired into a 20kg block of wood . which is attached to a spring horizontally . The velocity of the bullet is 350m/s. if the spring constant is 30 N/m. how does the spring compress?

3/ A 200g block connected to a light spring for which the force constant is 5.00N/m is free to oscillate on a horizontal , frictionless surface . The block is displaced 5.00cm from equilibrium and released from rest as in figure.

A/ find the period of its motion

B/ Determine the maximum speed of the block

شكرا لكم مقدما
