What does it mean when velocity = acceleration
What does the position, velocity, and acceleration graph look like of a person throwing a ball at a wall? I'm not considering the motion when the ball bounces back, only the motion from when the ball leaves the person's hand and hits the wall. Thanks.
What happens to the acceleration and velocity of an Apache helicopter when it fires a rocket-propelled missile at an enemy tank in front of it? How about the torque exerted by the missile? After launching a missile, will the helicopter's speed be faster, slower, or stay same? Does the pilot have to correct for pitch, yaw, or roll? Provide your reasoning. What parameters would you need to figure those accelerations?
Does the acceleration of a sled down a track depend on the initial velocity the team can give it (a push)? Does the velocity of a sled down the track depend on the initial velocity the team can give it? Does the acceleration of a sled down a track depend on the weight of the team members? Please answer in in sentences!
in which of the below cases does an object slow down: A. the velocity and acceleration vectors point in opposite directions B. the acceleration is negative C. the slope in the velocity-vs-time graph is negative D. velocity and acceleration vector point in the same direction E. the acceleration is positive
The graph shows the kinematics (vertical position, velocity, and acceleration) of the center of gravity of a diver and the reaction force of the diving boar during the takeoff phase for a 3 1?2 backward somersault dive in the tuck position. a) At what time(s) (approximately) does the displacement of the diver change direction? How many times does this occur during the takeoff phase of the dive? b) When does the center of gravity accelerate in the upward direction and...
Below is the graph from the velocity of a particle. (a) When does the particle move forward? Move backward? Speed up? Slow down? (b) When is the particles acceleration positive? Negative? Zero? 2 CR
determine the angular velocity and the angular acceleration of the link 4 (?̇ 4 , ?̈ 4) and the velocity and the acceleration of the link 6 (?̇6 , ?̈6 ) by means of complex numbers when ?2=1 rad/s and ?2 = 0
Given s(t)-5t +10t, find (c) the velocity and acceleration when t-2 (a) vt) (b) a(t) (c) When t- 2, the velocity isfeet per second ее (Simplify your answer.)

What does a zero, negative and positive line-of-sight velocity dispersion for galaxies mean (physical interpretation)?
What does in sub mean?? An Iron-Nickel sample from a meteorite was placed into a velocity selector and mass spectrometer. Experimenters expect 3 primary isotopes: 56Fe, 58Ni, & 60Ni. Positive ions are accelerated by an applied potential (AV) of 3300 Volts which is the same potential difference used to create the electric field in the velocity selector, where d is 1.1 cm. 1. On the figure provided, in the velocity selector region, (A) draw the direction of the electric field....
