Answer:
Weight of cow = 7.59 lbs
Explanation:
Given:
Weight of cow = 1518 lbs
Find:
Weight of heart of a cow
Computation:
Note: It is not given that in the mammals the weight of heart is approximately 0.5% of total body weight
Weight of heart of a cow = [Weight of cow][0.5%]
Weight of cow = [1518][0.5%]
Weight of cow = 7.59 lbs
Answer:
Explanation:
height of the building h = 15 m
initial vertical velocity u = 0
v² = u² + 2 g h
u = 0 , final velocity after falling height h
h = 15
v² = 2 x 9.8 x 15
v = 17.14 m /s
. Time of fall be t
h = 1/2 g t²
15 = 1/2 x 9.8 x t²
t = 1.749 s
This time will be required for truck to come under the building .
speed = distance / time
distance = speed x time
= 22 x 1.749
38.5 m
Truck should be at a distance of 38.5 m . when the stuntman starts falling .
Answer:
Explanation:
<u>Given the following data;</u>
Initial velocity = 0 (since the stone is starting from rest).
Final velocity = 32 m/s
Acceleration = g = 10 m/s²
Time = 3.2 seconds
To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;
Where;
- V is the final velocity.
- U is the initial velocity.
- a is the acceleration.
- t is the time measured in seconds.
Substituting into the formula, we have;
<em>Proven: 32 m/s = 32 m/s</em>
The answer is A. Authoritarian
Authoritarian parents don’t trust their children to make good choices. They tend to be controlling. They also don’t give children choices or options and are not willing to negotiate which is very restrictive.
