A motorcycle starts from rest . If its gain an acceleration of 2m/s^2 in 5 second , Calculate the final velocity.

densk [106]

initial velocity=u=0m/s
Acceleration=a=2m/s^2
Time=t=5s
Final velocity=v=?

Using first equation of kinematics

$\\ \sf\longmapsto v=u+at$

$\\ \sf\longmapsto v=0+2(5)$

$\\ \sf\longmapsto v=10m/s$

Evaluate the expression 5(7 − 4)2 ÷ 3 + 11. (5 point)

ch4aika [34]

Remember PEMDAS.
Parentheses first, which is 3. So then that is 5 times 3 times 2 divided by 3 +11
Simplify, 15 times 2 divide 3 +11
30divide 3 +11

A mini basketball court has an area of 500

aivan3 [116]

Answer:

Step-by-step explanation:

let x,y be the sides of court.

2(x+y)=90

x+y=90/2=45

y=45-x

xy=500

x(45-x)=500

45x-x²=500

x²-45x+500=0

x²-25x-20x+500=0

x(x-25)-20(x-25)=0

(x-25)(x-20)=0

x=25,20

when x=25

y=45-x=45-25=20

when x=20

y=45-20=25

sides are 25 ft,20 ft.
