Answer:
W = 882 N
Step-by-step explanation:
Given that,
The weight of a person, W = 90 kg
The value of acceleration due to gravity, g = 9.8 m/s²
We need to find the weight of the person on Earth. The formula for the weight of an object is given by :
W = mg
Substitute all the values,
W = 90 kg × 9.8 m/s²
W = 882 N
So, the weight of the person is equal to 882 N.
Answer:
Step-by-step explanation:
g(2) = 2(2)= 4
f(4) = 4^2 + 2(4) = 16 + 8 = 24

4
Answer:
39.75
Step-by-step explanation:
First, subtract 50 from both sides
200z + 50 - 50 = 8000 - 50
200z = 7950
Then isolate the variable by dividing both sides by 200
200z/200 = 7950/200
z=39.75
Answer:
10.27 feet/sec.
Step-by-step explanation:
The distance traveled by the car, d in feet, is given by the function .......... (1), where t is the time in seconds.
So, at t= 2 sec, from equation (1) we get d = 1.1 × 4 = 4.4 feet.
Again, at t = 5 sec, we get d = 1.1 × 32 = 35.2 feet.
Now, average speed of the car from t = 2 sec. to t = 5 sec. will be give by
= feet/sec. (Answer)
