9) A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof one second later. a) If the height of the building is 20m, what must the initial speed of the first ball be if both are to hit the ground at the same time? b) What must the height of the building be for both balls to reach the ground at the same time if [| = 6 ?

You release a snowball from rest at the top of a 15 m tall platform. Your friend, directly belowyou, throws a snowball straight up at the same time. Your friend’s snowball leaves their hand1.75 m above the ground, traveling at 8 m/s.(a) Write expressions for the position of each snowball as a function of time, and determinehow much time it takes the two snowballs to reach one another. In other words, find thetime when both snowballs are at the same position.(b) How high above the ground are the snowballs when they meet?
1. The nearest grocery is 60 m, east from your house. You are walking at 1.2 m/s for 15.0 s toward the grocery when it started to rain and you ran back to your house to get an umbrella. It took you another 5.0 s to go back to your house. You start walking again at 1.2 m/s until you reach the grocery. (a) What is your average speed? (b) What is your average velocity?
A turtle crawls along a straight line, which we’llcall the x-axis with the positive direction to the right. The equationfor the turtle’s position as a function of time is x 1t2 = 50.0 cm +(2.00 cm/s)t - (0.0625 cm/s2)t2. How long after starting does it take the turtle to return to its starting point?

You can accelerate and brake on your bicycle with a maximum magnitudeof the acceleration of 3 (m/s)/s. Your top speed is 12 m/s. You want to drop ofyour physics textbook at your friend who normally works with an electronictextbook version, but just called and asked you for your printed copy for theafternoon. She lives 168m up the road from you. You need 11 seconds to runout of your apartment and grab your bike, and you need another 11s to run toyour friend’s apartment door to hand her the book after stopping with your bike.How long to you need in total to bring her the book?
The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explain

The centre of the cannon’s target (which has a radius of 1.0 m) ispainted on the asphalt 42.0 m away from the water cannon.Will the balloon hit the target? Justify your response with calculations that indicate where thewater balloon will land and make one suggestion about how to adjust the water cannon sothat the water balloon will hit the target.
