Answer:
39 miles
Explanation:
we will make your house to be the central point in the four cardinal points.
Please follow the diagram on the attachment to get the movement clearly.
First, you move to a dry cleaners 12miles east of your house, and then to a grocery store 15miles west of your house.
This means you must have moved back to your house before going to the grocery which is 15miles west of your house.
so to and fro from your house to dry cleaners = 12*2 = 24 miles.
Then the total distance you cover will be = 24 +15 = 39 miles
When the train reaches the bottom of the track and is traveling along the ground, its kinetic energy is 2,000 J.
Given; Mass m = 65.0 Kg; acceleration a = 1.25 m/s²
Required: Force F = ?
Formula: F =ma
F = (65.0 Kg)(1.25 m/s²)
F = 81.25 N
Magnetic forces can cause charged particles to move in circular or spiral paths. Particle accelerators keep protons following circular paths with magnetic force. The magnetic force is perpendicular to the velocity, and so velocity changes in direction but not magnitude. Uniform circular motion results.
