The red box must way more. Gravitational potential energy is the product of a an objects mass times the acceleration due to gravity (which is constant on earth) times its height. Since the objects are on the same shelf they are at the same height, and since gravitational acceleration is constant as long as we stay on planet earth, then the mass is the only possible thing that could have changed. This means that the red box must weigh more than the blue box.

A mass m = 550 g is hung from a spring with spring constant k = 2.8 N/m and set into oscillation at time t = 0. A second, identi
riadik2000 [5.3K]

Answer:

The second system must be set in motion t=0.70s seconds later

Explanation:

The oscillation time, T, for a mass, m, attached to spring with Hooke's constant, k, is:

T=2\pi\sqrt(\frac{m}{k} )

One oscillation takes T secondes, and that is equivalent to a 2π phase. Then, a difference phase of π/2=2π/4, is equivalent to a time t=T/4.

If the phase difference π/2 of the second system relative to the first oscillator. The second system must be set in motion t=\frac{\pi}{2}\sqrt(\frac{m}{k})=\frac{\pi}{2}\sqrt(\frac{0.55}{2.8}= 0.70s) seconds later

A car moving along a straight road at 30m/s slows uniformly to a speed of 10m/s in a time of 5s. determine the
nignag [31]

Answer:

A=ACCELERATION = -4 m/s^2

B=DISTANCE= 72 m

Explanation:

Solving for the acceleration of the car

A= (10 m/s-30 m/s) / 5s

A= -20 m/s / 5s

A= -4 m/s^2

Solving for the distance traveled after the third second

D= v1 * t + 1/2at^2

D= 30 m/s * 3 s + -2m/s^2 * (3s)^2

D= 90 m + - 18 m

D = 72 m
