After a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by:v = 1.2 i - 9.8t jwhere v is in meters per second and t is in seconds. The ball’s displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by:Δ⃗r=∫00.380s⃗vdtTo perform the integral, you can use the calculus theorem:∫[A+Bf(x)]dx=∫Adx+B∫f(x)dx You can think of the units and unit vectors as constants, represented by A and B. Perform the integration to calculate the displacement of the ball from the edge of the table at 0.380 s

I am having trouble with a 3d motion problem. The problem is as follosw, "At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of i = (3.00 i - 2.00 j) m/s and is at the origin. At t = 2.00 s, the particle's velocity is = (7.00 i + 8.20 j) m/s. (Use the following as necessary: t. Round your coefficients to two decimal places.)" The problem asks me to find acceleration of the particle at any time t and to find its coordinates at any time t. Thanks for the help

1A. You're feeding the fish at the pond by the baseball field and decide to do some physics calculations. You notice that you release the fish food 1.65 m above the surface of the water, and during one throw, when the food left your hand at 3.20 m/s with a direction of 13.0° below the horizon, you managed to hit a fish near the surface. How fast was the food going right before it hits the fish? 1B.Two kittens are running toward each other, one is named Chloe and the other is named Luna. Luna runs at a speed of 1.40 m/s.

1. Andrew and Kevin decide to try out the physics ideas that they are learning and take their baseball pitching machine and a baseball to a 96 feet tall local building. Based on what they have learned the height, s(t), of a baseball, thrown straight up with an initial speed of 80 feet per second from a rooftop 96 feet high is s(t)=-16t^2+80t+96 where t is the elapsed time that the baseball is in the air. The baseball that is pitched miss the rooftop on their way down and eventually strike the ground. a) What is the average velocity of a baseball from t=0 to t=2 seconds? b) What is the velocity of the baseball 2 seconds after it is thrown? c) After how many seconds will the velocity of the baseball reach zero? d) What is the velocity of the baseball t seconds after it is thrown? e) What is the velocity of the baseball as it passes the roof top on the way down?
