The answer is $6
when you arrange the numbers in order and use order of elimination, 6 is left in the middle
Answer:
566.3 m
Explanation:
The distance travelled by the object can be found by using the SUVAT equation:
where
u is the initial velocity
t is the time
a is the acceleration
For the object in this problem:
u = 19 m/s
a = 2.5 m/s^2
Substituting t = 15 s, we find the distance travelled:
Given:
F = 4.719 N, the applied force
a = 33 m/s², the acceleration
Let m = the mass.
By definition,
F = m*a
Therefore,
m = F/a
= (4.719 N)/(33 m/s²)
= 0.143 kg
Answer: 0.143 kg
Answer:
<u>196 J</u>
Explanation:
<u>Formula</u>
- Work done(W) = Mass (m) x gravity (g) x height (h)
<u>Here, we are given</u> :
- m = 8.0 kg
- g = 9.8 m/s² (on Earth)
- h = 2.5 m
<u>Solving</u>
- W = 8 × 9.8 x 2.5
- W = 20 × 9.8
- W = <u>196 J</u>
