A horizontal net force F is exerted on a 2.0 kg object at rest. The object starts at x = 0m and travels 6.0 m along a horizontal frictionless surface. The net force F as a function of the object's position x is shown below. What is the velocity of the object?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass
