Explanation:
Newton thus the S I unit of force is newton
Answer:
19.53 cm
Explanation:
The computation of the height is as follows:
Here we applied the conservation of the energy formula
As we know that
P.E of the block = P.E of the spring
m g h = ( 1 ÷ 2) k x^2
where
m = 0.15
g = 9.81
k = 420
x = 0.037
So now put the values to the above formula
(0.15) (9.81) (h) = 1 ÷2 × 420 × (0.037)^2
1.4715 (h) = 0.28749
h = 0.19537 m
= 19.53 cm
Hi! Let's see.
<h3><u>TOPIC: Kinetic Energy.</u></h3>
Explanation:
Data:
- Mass(m) = 2.1 kilograms
- Speed(v) = 30 m/s
- Kinetic Energy(Ek) = ?
==================================================================
Use the kinetic energy formula:
Replace by the data:
We multiply speed squared:
Multiply in the numerator, without forgetting the units:
Both numerator and denominador operations are divided:
Answer: The kinetic energy is <u>945 Joules.</u>
