A skateboarder travels on a horizontal surface with an initial velocity of 3.2 m/s toward the south and a constant acceleration of 2.2 m/s2 toward the east. Let the x direction be eastward and the y direction be northward, and let the skateboarder be at the origin at t=0. What is her x position at t=0.80s? What is her y position at t=0.80s? What is her x velocity component at t=0.80s? What is her y velocity component at t=0.80s? Express your answer to two significant figures and include appropriate units.

You throw a tennis ball North with an initial speed of 24 feet per second, at an angle of elevation 30° above horizontal, releasing the ball 4 feet above the ground. A steady wind imparts a constant acceleration of 3 feet per second squared Eastward. Acceleration due to gravity is a constant 32 feet per second squared downward. Throughout the problem, let East be the positive x direction, North the positive y direction, and up the positive z direction. Let...

An electron, with an initial horizontal velocity of magnitude 5.60 × 109 cm/s, travels into the region between two horizontal metal plates that are electrically charged. In that region, it travels a horizontal distance of 2.93 cm and has a constant downward acceleration of magnitude 7.18 × 1017 cm/s2 due to the charged plates. Find (a) the time required by the electron to travel the 2.93 cm and (b) the vertical distance it travels during that time. Also find the...
