Answer:
<u>Acceleration is 2 m/s² </u>
<u>Distance</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u>0</u><u> </u><u>m</u>
Explanation:
From definition of acceleration, Acceleration is the rate of change in velocity.
• Simplifying the definition, or modifying it;
• Let's formulate symbols:
- a is acceleration
- v is final velocity, v = 20 m/s
- u is initial velocity, u = 0 m/s [ at rest ]
- t is time, t = 10 seconds
Distance = ut + ½at²
Distance = (0 × 10) + (½ × 2 × 10²)
Distance = 0 + 10²
Distance = 100 meters
Observations are generally recorded in journal form, while results can be compiled into tables, charts or graphs. Knowing the difference between the two makes it much easier to analyze your data and come up with conclusion, this gives your conclusion support as well as reliability. Both together show data from the experiment preformed.
Answer:
a)v=5.81 m/s
b)N= 831.77 N
Explanation:
Given that
m = 39 kg
r= 2.98 m
T= 416 N
a)
Lets take speed of the boy at the lowest position is v m/s
The radial force Fc
The tension in the chain is T
Now by putting the values
v²=33.77
v=5.81 m/s
b)
Lets take normal force = N
Now by putting the values
N= 831.77 N
