Answer: velocity = 79.6m/s, distance covered = 139.6m and velocity when distance is 10.0m = 61.611m/s
Explanation:
First step is to take a direction of motion, so to avoid issues with negative sign, I take my direction of motion as the positive y axis which makes the parameters positive.
The object is of a free fall thus it has a constant acceleration of g = 9.8m/s².
a) initial velocity (u) = 60m/s, g = 9.8m/s², time taken (t) =2s, we need to get velocity at that time using the formulae below
v = u + at
v = 60 + (9.8)* 2
v = 60 + 19.6
v = 79.6m/s
b) to get the distance traveled at t =2s, we use the formulae below
s =ut + 1/2at² where s = distance covered.
s = 60 * 2 + 1/2 * 9.8 * 2²
s = 120 + 1/2 *9.8 * 4
s = 120 + 9.8 * 2
s = 120 + 19.6
s = 139.6m
c) to get the velocity (v) when distance traveled (s) = 10m, we use the formulae below.
v² = u² + 2as
v² = 60² + 2( 9.8)(10)
v² = 3600 + 196
v² = 3796
v = √3796
v = 61.611m
Answer:What are the statements?
Explanation:
Answer:
Incident solar radiation.
Explanation:
Isolation is defined as the solar radiation that reaches surface of the earth. Isolation term is derived from the word solar radiation. It is mainly applied to radiation which is first arriving earth atmosphere, and then second arriving earth surface.
Isolation is measured by the amount of incoming solar energy received by the earth per square centimeter per minute. Isolation affects some factors such as temperature, the more the isolation cause higher the temperature.
