Answer:
94 kg or 921.6 N
Explanation:
The velocity function is 
. The acceleration function, a(t), is the time derivative of the velocity function.
At 
,
Because the elevator is going upwards, the net acceleration, 
where g us acceleration of gravity.
The resultant weight is
Since the bathroom scale is graduated in kg, it's reading is
Option 3.
Neptune Uranus Saturn Jupiter Mars Earth Venus Mercury.
Acceleration is the rate of change of the velocity of a moving object. To determine the speed the object has at a certain time, we need to determine the acceleration first by dividing the speed with the time given. We do as follows:
acceleration = 4.9 m/s / 5.1 s = 0.96 m/s^2
To determine the velocity after 7.1 s, we multiply 7.1 s to the acceleration.
speed or velocity = 0.96 x 7.1 = 6.52 m/s
Answer:
10 Sig Figs
Explanation:
Just start counting at the first non zero after the decimal so in this case the nine, and count all of the numbers including zeros after that.
