A roller coaster accelerates from an initial velocity of 5.0 m/s to a final velocity of 80 m/s during a 5 second time interval. At what rate does the roller coaster accelerate?
displacement
Velocity =
time
(n=4)
Acceleration =
final velocity – initial velocity

15 m/s2
15 m/s
-15 m/s2
17 m/s2

15m/s^2

Step-by-step explanation:

u=5m/s

v=80m/s

a=?

t=5sec

now

a=v-u/t

a =80-5/5

a=75/5

a =15 ans

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
