A golfer hits a golf ball up a hillside, in a trajectory given y= -0.0015x^2 + 0.5x, where y is the vertical height of the ball and x is the horizontal distance of the ball , both in yards. the hillside has a slope 1/8 . if ihe point of impact with the ball is at the origin, then what are the landing coordinates.

Answer the following questions for the given problem: A ball is thrown up into the air. The ball’s height , h (in feet), from the ground is modeled by h(t) = -16t2 + 64t +5, where t is measured in seconds. Before answering these questions, think about the practical meaning of the vertex, y intercept and x intercepts, and how they apply to this problem. 1. What is the height of the ball at its highest point? 2. How many...

Homework 3 As you know very well from physics, if you hit a ball forward with a certain angle and a certain speed, it makes an orbital movement. The height of the ball is determined by the equation given below. y(t)=y_0+v_y0 t-1/2 gt^2 Where y0 is the first location of the ball, vy0 is the initial vertical velocity of the ball and g is the gravitational acceleration. After the ball is thrown, the horizontal distance is determined by the following...

Basic Physics: Projectile Motion. 1. Given that a ball is launched perfectly horizontally from a height of 1.2 meters, and lands on the floor a horizontal distance of 2.6 meters away, find the initial speed (or "muzzle velocity") of the ball in meters per second. Use 9.82 meters per second for "g". 2. A ball is launched at an angle of 56.5 degrees up from the horizontal, with a muzzle velocity of 7 meters per second, from a launch point...

Suppose you are climbing a hill whose shape is given by the equation z = 900 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (120, 80, 764). The positive x-axis points east and the positive y-axis points north. (a) If you walk due south, will you start to ascend or descend? ascenddescend     At what rate? vertical meters per horizontal meter (b) If you walk northwest, will...

1) A ball of 2 kg rolls without slipping along a horizontal floor with a velocity of 10m/s. 1a) find the rotational kinetic energy of this ball. 1b) Now, the ball rolls up an inclined ramp (rolls without slipping). What height does the ball reach along the ramp before it finally stops? 2) Consider a stick of total mass M and length L rotates about one end. Since the stick gets heavier as you move along a stick, the stick...
