What happens to velocity if mass is quadrupled? What happens to acceleration if mass is quadrupled?
If you quadrupled the mass and quintupled the radius of a planet, by what factor would g at its surface change?
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?
Write the functions that give the velocity and acceleration of a mass moving with position ?(?) = 3 cm cos(2 ? 12 Hz ? + 0.1). What units do the mass’s position, velocity, and acceleration have?
1. What is the linear (translational) analog for torque? A. Mass B. Acceleration C. Velocity D. Force 2. What is the linear (translational) analog for the 'moment of inertia'? A. Velocity B. Mass C. Force D. Acceleration 3. The torque on a lever arm is maximized when the force is forming what angle with the lever arm? A. 45 degrees B. 90 degrees, or perpendicular to the lever C. 60 degrees D. 0 degrees or parallel to (alongside) the lever
What happens to the motion of an object under the influence of a single constant force as you decrease the object’s mass? A) the magnitude of the acceleration would increase B) the magnitude of the velocity would increase but the acceleration would remain the same C) the magnitude of the acceleration would decrease D) the magnitude of the velocity involved would decrease but the acceleration would remain the same
If the spring constant of a simple harmonic oscillator is quadrupled, by what factor will the mass of the system need to change in order for the frequency of the motion to remain the same? manal minitial
A 3.70 kg mass is observed to have a constant acceleration from an initial velocity of 2.44/m/s to a final velocity of (18.9/-10.7 j) m/s in 2.91 s. Two forces act on the mass: gravity (F_G = -36.26 j N) and an unknown applied force F. Determine the acceleration and unknown force.
A. Write equations for the position, velocity, and acceleration of the mass as a function of time. These equations express what physicists call simple harmonic motion (SHM): B. In our equations above, we have assumed there is no damping (i.e. friction, air drag etc.) to decrease the amplitude of the motion. If you watch the motion of the mass for even a short amount of time, you do see the effects of damping. What should we include in our equations...
8. A sky diver reaches a terminal velocity of 120 mph. What will the acceleration of the diver be? 2. 9. A 40 N object encounters 25 N of air resistance. What is the acceleration? 10. | A bug collides with a bus with a Force of O.2 N. The mass of the bus is 7500 kg, and the mass of the bug is 0.05 kg. resulting accelerations compare? How do the
