Adog runs with an initial speed of 1.5 m/s on a floor. it slides to a stop with an acceleration of -0.35 m/s^2. how long does it take for the dog to stop?

3.214 m

Explanation:

Here object is moving in a constant acceleration. Then we can use motion equations to find the total distance

V² = U² + 2as

0 = 1.5² + 2×-0.35 × s

s = 3.214 m

symbols has usual meanings.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
