A mass and spring are arranged on a horizontal, frictionless table as shown in the figure below. The spring constant is k = 480 N/m, and the mass is 4.8 kg. The block is pushed against the spring so that the spring is compressed an amount 0.31 m, and then it is released. Find ...

the force exerted by a spring increases as the spring stretches. imagine that you attach a heavy object to one end of a spring and then, while holding the springs other end, whirl the spring and object in a horizontal circle. does the spring stretch. explain

In a physics lab experiment, a spring clamped to the table shoots a 18 g ball horizontally. When the spring is compressed 20 cm, the ball travels horizontally 4.9 m and lands on the floor 1.3 m below the point at which it left the spring. What is the spring constant?

A 0.63-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.13 to 0.22 m (relative to its unstrained length), the speed of the sphere decreases from 5.95 to 4.75 m/s. What is the spring constant of the spring? (The sphere hangs from the ...

Physics - Spring
Suppose a 1.5kg block of wood is slid along a floor and it compresses a spring that is attached horizontally to a wall. The spring constant is 555N/m and the block of wood is traveling 9.0m/s when it hits the spring. Assume that the floor is frictionless and the spring is ...
