Solve the following motion problems. 1. A ball is thrown vertically from a point 30 feet above the ground. (a). At what velocity must it be thrown for it to strike the ground in 2 seconds? Is the ball initially thrown vertically upward or downward? (b). What is its velocity when it strikes the ground? (c). Where is the ball one second after it was thrown initially? Is it moving upward or already on its way down? (Hint: Take the time and displacemnet at the maximum point of its flight by setting v=0.)

I'm not sure how to solve this! I tried and got 1.3 / 2.4 seconds. Am i right? Could you explain how to do it if i'm not? Cheers ! In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window. If the loaf of bread leaves Jerry's hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m? Round to the nearest tenth of a second.
Can you help me solve this problem please?A hot air ballon is rising into the air with a constant velocity of 4.75 m/s. The person riding in the hot air ballon drops a bag of flour when the balloon is 18.5 m from the ground. How long does it take the bag to hit the ground after it has been released?
How do you calculate the total time a projectile is in flight given only the initial velocity and maximum height?
A golfer wants to put the ball into the final hole which lies 7.0 m away from the ball and up a slight hill. Because of the incline while the ball moves up this hill will experience a constant deceleration of 1.8 m/s^2. Which initial velocity should the golfer give the ball if they want to make it go precisely into the hole? Please answer in m/s
You are on the roof of a Physics Building, 21 m above the ground. Your physics professor, who is 1.71 m tall, is approaching the building at constant speed of 2.04 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg?
A person standing at the edge of a cliff throws a rock upward from a height of 350ft above ground level with an initial velocity of 65⁢ft/s. What is the velocity of impact when the rock reaches the bottom of the cliff? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places. (Hint: Use h(t)=−16t2+65t+350 as the position function, where hh is in feet, tt in seconds. Ignore air resistance.)
A firework is projected from the level ground in such a way that v0y = 10m/s and v0x = 20 m/s.a) Find the time it takes the firework to reach its maximum height reached.b) Since the firework returns to the ground, it has the same initial and final height. Whenthis happens, the time it takes the object to land is twice the time it takes to reach its maximum height. Using this information, find the horizontal and vertical components of the velocity of the firework right as it lands.
A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.00 m/s, and her takeoff point is 1.80 m above the pool. How long are her feet in the air? Answer in 2 decimal places. What is her highest point above the board? Answer in 2 decimal places. What is her velocity when her feet hit the water? Answer in 2 decimal places.
Which of the following is the correct conversion of initial velocity in base SI units? Refer to the problem given below. Lamborghini Murcielago is one of the most iconic cars ever as it was featured as a Batmobile in the third installment of Batman Trilogy directed by Christopher Nolan. If it can go from 0 to 60 miles per hour in 3 seconds, what is its rate of change in velocity per unit time? (1 mile is equal to 1.61 kilometers)
Draw motion diagrams for (a) an object moving to the right at constant speed, (b) an object moving to the right and speeding up at a constant rate, (c) an object moving to the right and slowing down at a constant rate, (d) an object moving to the left and speeding up at a constant rate, and (e) an object moving to the left and slowing down at a constant rate. (f) How would your drawings change if the changes in speed were not uniform, that is, if the speed were not changing at a constant rate?
