Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Problem: A person who is 1.3 m tall throws a ball with a speed of 19m/s at an angle of 17 degrees above horizontal. One part of the problem asks me to find the x and y components of the ball's velocity before it hits the ground. I have tried using the vy^2 = voy^2 + 2ah for the y-component: vy^2 = (5.56)^2 + (2)(10)(1.3) = 7.54 and my x-component is just (19)(cos(17))= 18.17 m/s, but it is saying this is not the right answer. What am I doing wrong?

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
The position vector of a particle is r(t). Find the requested vector. 1. The velocity at t = pi/4 for r(t) = 2sec2(t) i - 6tan(t) j + 4t2 k. 2. The acceleration at t = 3 for r(t) = (5t - 2t4) i + (9 - t) j + (8t2 - 9) k.
(a) If a person can jump a maximum horizontal distance (by using a 45 projection angle) of 3.0 m on Earth, what would be his maximum range on the Moon, where the free-fall acceleration is g/6 and g = 9.80 m/s2? (b) Repeat for Mars, where the acceleration due to gravity is 0.38g.
(a) Repeat the problem two problems prior, but for the second leg you walk 20.0 m in a direction 40.0° north of east (which is equivalent to subtracting B from A that is, to finding R=AB ). (b) Repeat the problem two problems prior, but now you first walk 20.0 m in a direction 40.0° south of west and then 12.0 m in a direction 20.0° east of south (which is equivalent to subtracting A from B that is, to finding R=BA=R ). Show that this is the case.
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=1.2i9.8tj where v is in meters per second and t is in seconds. The balls 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 r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(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.
