Answer:
kinetic energy = 1 / 2 mv²
kinetic energy = 1 / 2 × 20 × 10 ²
kinetic energy = 1000 joules
.........
I'm pretty sure its D. Both B. and C.
Answer:
When radius of star increase by 6 factor then area of star will increase by a factor of 36.
Explanation:
As we know that
Area of star A given as
Where R is the radius of star.
Area of star when radius become 6 times
So
We can say that when radius of star increase by 6 factor then area of star will increase by a factor of 36.
Answer:
Explanation:
You need to look at this in 3 separate stages, and then sum thedistance from each stage:
Stage 1)
a=2
t=20
=0
We also need to find the final velocity
Stage 2)
a=0
v=40
t=20
Stage 3)
a=-3
=40
=0
So the total distance is
