## How fast will an object with a mass of 15 kg accelerate if a force of 72 N is constant applied to it?

The acceleration is 4.8ms2 .

What is acceleration of 20N and 2kg?

20 N=2 kg×a. so. a=10 m/s2→ read this as 10 meters per second squared, or 10 meters per second every second.

How do you find weight with mass and acceleration?

Summary

1. According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a=Fm.
2. This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

### What is the velocity of a block of 2 kg?

A block of mass 2.0 kg is moving on a frictionless horizontal surface with a velocity of 1.0 m/s (figure 9-E12) towards another block of equal mass kept at rest. The spring constant of the spring fixed at one end is 100 N/m.

What is the initial velocity of the spring in Bloch’s experiment?

Two rectangular blocks A and B of mass 2kg & 3kg respectively are connected by spring of k=10.8N/m & are placed on a frictionless horizontal surface. The Bloch A was given an initial velocity of 0.15m/s. What is the max compression of the spring? – Quora

What is the spring constant of frictionless floor?

(14 pts) A 0.180 kg block is initially held against a spring with spring constant 18.0 N/m. The spring is compressed a distance 0.200 m from its equilibrium position. This block, as well as a second block of mass 0.225 kg is at rest on a frictionless floor.

## How does a frictionless spring work?

This block, as well as a second block of mass 0.225 kg is at rest on a frictionless floor. The spring is then released suddenly and the 0.180 kg block slides to the right, detaching from the spring, and then collides with the other block, sticking to it.
