A ball is tossed up vertically from ground level and returns to earth 6 s later. What was the initial velocity of the ball and how high did it go?

initial velocity = 29.4m/s

maximum height = 44.1m

Step-by-step explanation:

This problem is a projectile motion. The ball is tossed vertically from the ground, which means the angle between the ball and the horizontal is 90°

° (the ball is tossed vertically)

2Usinα = g*T

2U =gT/sinα

2U = 9.8* 6/ sin90°

2U=58.8

U = 58.8/2 =29.4

U=29.4m/s

maximum height attained (H) =

=

maximum height =44.1m

1/5

step-by-step explanation:

the dice has 6 sides and there is only one 5 in a dice.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
