Answer: 3km E, 1km N
Explanation:
4E + 6S + 3E + 5N + 10W + 8N + 3S= 3W, 1S
3W, 1S= 3E, 1N
F = mass × acceleration
17 = mass × 5
mass = 17/5
The RATE of change of position is speed.
The term pressure refers to the force per area created by the weight
of anything whose weight is distributed over an area, such as the
Earth's atmosphere, a lake, a gas inside a sealed jar, or a pointy
high heel.
Strange as it may seem, that's true. (choice 'a'.)
"Acceleration" doesn't mean "speeding up". It means ANY change in
the speed or direction of motion. So a car with the brakes applied
and slowing down, and a point on the rim of a bicycle wheel that's
turning at a constant rate, are both accelerating.
