Explanation:
v = u + at
25 = 75 + a * 5
25 = 75 + 5 a
a = 25 - 75/5
a = -50/5
a = -10m/sec^2

Your answer is B :) because well the conditions are harsh.
Answer:
The total power radiated by the sun is 3.71×10^26W
Explanation:
The Earth is spherical in shape
Therefore, Area = 4πr^2 = 4×3.143×(1.489×10^11)^2 = 2.79×10^23m^2
Power radiated by the Sun = solar radiation on Earth × Area = 1330W/m^2 × 2.79×10^23m^2 = 3.71×10^26W
Answer:
blocks of ice are usually covered with cloth or sawdust while being stored
Force = change in momentum / impact time
= mass (change in velocity) / impact time
= 0.07 (0.5-0) / 0.5
= 0.07N
