Answer:
m = 77.3 kg
Explanation:
Time period of spring block system is given as
here we know
m = mass
k = spring constant
so now we have
so we have
Now time period of chair + astronaut is 2.23 s
so we have
The answer is chemical energy.
In our body, our chemical energy comes in the form of glucose. It is glucose that is turned into mechanical energy in our body. When we move, our muscles act as a transducer. As muscles contract, they convert the glucose in our body into mechanical energy. The mechanical energy in our muscles is also called muscular energy.
The time taken for the plant to hit the ground from a distance of 7.01m and at a velocity of 8.84m/s is 1.59s.
<h3>How to calculate time?</h3>
The time taken for a motion to occur can be calculated using the following formula:
v² = u² - 2as
Where;
- v = final velocity
- u = initial velocity
- s = distance
- a = acceleration
8.84² = 0² + 2 × a × 7.01
78.15 = 14.02a
a = 5.57m/s²
V = u + at
8.84 = 0 + 5.57t
t = 1.59s
Therefore, the time taken for the plant to hit the ground from a distance of 7.01m and at a velocity of 8.84m/s is 1.59s.
