A 4.00 kg cart is pushed against a spring at point A, compressing the spring (with a spring constant of 600 N/m) by 0.816 m. When the cart is released from rest, it moves to the right with a constant speed (assume there is no friction in the wheels). What is the speed of the cart after it is released at point B?

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?

What is the wavelength of an earthquake wave if it has a speed of 8 km/s and a frequency of 3 hz?
