A basketball player dribbling down the court usually keeps his eyes fixed on the players around him. He is moving fast. Why doesn’t he need to keep his eyes on the ball?
between points in a plane do not change when a coordinate system is rotated In other words, the magnitude of a vector Is invariant under rotations of the coordinate system. Suppose a coordinate system S is rotated about its origin by angle to become a new coordinate system S’, as shown in the following figure. A point in a plane has coordinates (x,y)in S and coordinates (x,y) in S’. (a) Show that, during the transformation of rotation, the coordinates in S are expressed in terms of the coordinates in S by the following relations: {x=xcos+ysiny=xsin+ycos (b) Show that the distance of point Pto the origin is invariant under rotations of the coordinate system. Here, you have to show that x2+y2=x2+y2. (c) Show that the distance between points Pand Q is invariant under rotations of the coordinate system. Here, you have to show that ( xP =xQ )2+( yP yQ )2=( xP =xQ )2+( yP yQ )2 .
Maximum height the projectile reaches: 23.948m Projectile speed at max height: 28.751m/s Earliest time when the height of the projectile is half of its maximum value: 0.648s I have tried this problem many times and I cannot get the correct answer. I have attached both the problem and a picture of my work, which is incorrect. What am I doing wrong?
Question 2 The situation is the middle image. I add a particular horizontal velocity to both. The masses are the same. • M = 8 kg • m = 2 kg • V = 3 m/s î + 5 m/s ĵ • v = 3 m/s î - 20 m/s ĵ %3D %3D You might figure out the center-of-mass velocity on your own. The next question will give the center-of- mass velocity, letting you confirm your answer. Calculate the total kinetic energy of the system (in Joules).
