An object of unknown mass, moving east with a momentum of 200.0 kg·m/s initially, experiences an impulse of 100.0 N·s delivered to it by a force due South. Find the object’s final momentum (both magnitude and direction).

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

What is a good example of instantaneous speed

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
