Answer:
Explanation:
The detailed steps and appropriate integration and differentiation is as shown in the attached files.
au = −g − kv2
ad = −g + kv2
(ff) fortissimo means very loud
Answer: 4.24m/s²
Explanation:
Acceleration is defined as change in velocity of an object with respect to time. Mathematically,
Acceleration (a) = Change in velocity/time taken
Acceleration (a) = final velocity (v) - initial velocity (u)/time taken (t)
Final velocity = 700m/s
Initial velocity = 0m/s (object beginning from rest)
Time taken = 2.75mins = (2.75 × 60)secs = 165seconds
Substituting the values in the acceleration formula a = v-u/t
a = 700-0/165
a = 4.24m/s²
Answer:
1040N
Explanation:
Given parameters:
Mass of the person = 100kg
Acceleration due to gravity = 10.4m/s²
Unknown:
Weight = ?
Solution:
The weight is the vertical force impacted by gravity on a body.
So;
Weight = mass x acceleration due to gravity
Weight = 100 x 10.4 = 1040N
The temperature in which water is frozen.
