A 1.0-kg object is suspended from a spring with k 16 N/m. The mass is pulled 0.25 m downward from its equilibrium position and allowed to oscillate. What is the maximum kinetic energy of the object? O 0.25 J O 1.0J O 2.0J 0.50 J 8:14 AM 30°C Mostly cloudy O ENG 23/09/2021

To test the resiliency of its bumper during low-speed collisions, a 4 490-kg automobile is driven into a brick wallI. The car's bumper behaves like a spring with a force constant 6.00 x 106 N/m and compresses 3.36 cm as the car is brought to rest. What was the speed of the car before impact, assuming no mechanical energy is transformed or transferred away during impact with the wall? m/s

A string with a bowling ball tied to its end is attached to the ceiling. The string is pulled back such that it makes a 10 degree angle with the vertical and it is then released. When the bowling ball reaches its lowest point, it has a speed of 2 m/s. What is the frequency of this bowling ball-pendulum?

What is the acceleration of the styrofoam ball? Position Curve: y = A x ^ 2 + B x + C A = -884 cm/s^2 B = 583 cm/s C = -24.4 cm RMSE = 3.94 cm Velocity Curve: y = A x + B A = -1.68e+3 cm/s/s B = 533 cm/s RMSE = 57.4 cm/s r: -0.943

15 MCQS A block of mass m = 5 Kg is attached to a spring of spring constant k. The block oscillates in simple harmonic motion on a frictionless horizontal surface. The block-spring total mechanical energy is 14.4 J. The maximum velocity of block, vmax, is: 2.4 m/s O 3 m/s O 2.1 m/s O 1.8 m/s 3.8 m/s A simple pendulum is set into motion at two different times with different initial conditions. The first time: the bob is in its equilibrium position and is given an

A 0.40 kg ball is suspended from a spring with spring constant 12 N/m. If the ball is pulled down 0.20 m from the equilibrium position and released, what is its maximum speed while it oscillates?

7. A block of mass m slides with constant velocity v down a plane inclined at 0 with the horizontal. During the time interval At, what is the magnitude of the energy dissipated by friction? (a) mgv At tan 0 (b) mgv At sin 0 (c) 1/2 mv3 At (d) The answer cannot be determined without knowing the coefficient of kinetic friction.
