Arock is thrown upward with a velocity of 20 meters per second from the top of a 24 meter high cliff, and it misses the cliff on the way back down. when will the rock be 10 meters from the water, below? round your answer to two decimal places use the gravity formula its a cluster in my brain

(a)

(b)

Step-by-step explanation:

(a)

We are given

velocity is 20 meters per second

the top of a 24 meter high cliff

so,

now, we can use gravity formula

now, we can plug value

(b)

we are given

h(t)=10

we can set it and then we can solve for t

now, we can use quadratic formula

we can compare and find a,b and c

a=-49 , b=200 , c=100

we get

we know that

time can never be negative

so,

Correct to 2 decimal places

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
