A small block of mass 250-g is connected to two springs with spring constant k1 (20N/m) and k2 (40N/m, both springs have not been stretched either compressed). The system is set at vertical position (K1 connected to a ceiling, block in middle, K2 connected to ground). (a) Find the equilibrium position of the block (b) Prove the block performs SHM with a small displacement from its equilibrium position Find the frequency of the SHM

Adelivery truck leaves a warehouse and travels 2.60 km north. the truck makes a left turn and travels 1.25 km west before making another right turn to travel 1.40 km north to arrive at its destination. what is the magnitude and direction of the truck's displacement from the warehouse?

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?
