Anna Shcherbakova is a 2022 Beijing Olympics figure skating gold medalist for ladies’ singles.After warming up she starts her practice by skating towards the middle of the ice rink, 14 metersfrom the entrance. However, this time, one of her friends decided to trick her by pushing hertowards the middle at a velocity of 1.2 m/s (disregard friction between the ice and her skates).Recovering from the shock 2 seconds after, she starts pushing herself forward at an accelerationof 0.5 m/s2. What velocity will she have when she reaches the middle of the rink?
A lunar lander is descending toward the moon’s surface.Until the lander reaches the surface, its height above the surface of themoon is given by y(t) = b - ct + dt2, where b = 800 m is the initialheight of the lander above the surface, c = 60.0 m/s, and d = 1.05 m/s2.(a) What is the initial velocity of the lander, at t = 0? (b) What is thevelocity of the lander just before it reaches the lunar surface?

You throw a ball up with the initial velocity 2.5 m/s. What is the velocity of that ball when it reaches the half of the maximum height? The mass of the ball is 0.340 kg.
A springbok is an antelope found in southern Africa that gets its name from its remarkable jumping ability. When a springbok is startled, it will leap straight up into the air—a maneuver called a “pronk.” A particular springbok goes into a crouch to perform a pronk. It then extends its legs forcefully,accelerating at 35 m/s2 for 0.70 m as its legs straighten. Legs fully extended, it leaves the ground and rises into the air.a. At what speed does the springbok leave the ground?b. How high does it go? We are doing this for physics homework, and I am so lost right now. Can I get some step by step or explanation as how to do this please?

You are on the roof of the lecture hall, 51.8 m above ground. As your physics professor, who is 1.8 m tall, walks towards the hall at a constant speed of 1.2 m/s. If you wish to drop an egg on your professor's head, where should the professor be when you release the egg? Assume egg is in freefall and air resistance is ignored.
