The frequency of vibration of a mass m suspended from a spring constant k us given by the relation F=Cm^xK^y is the dimensionless constant determine x and y

A projectile leaves the ground at an angle 30° to the horizontal. The kinetic energy is E neglecting the air resistance . Find in terms of E it's kinetic energy at the highest point of motion

you are below deck in a ship, in a room with no windows. there are lamps hanging down from the ceiling and there are marbles on the flat floor. by seeing if the lamps hang straight down and if the marbles start to move about, what can u tell?

A. you can tell whether you are moving or at rest.

B. you can tell whether you are accelerating or not.

C. you can tell whether you are changing speed but cannot tell whether you are changing direction.

D. you can tell whether you are changing direction but cannot tell whether you are changing speed.

a child of mass 40 kg slides down a water slide that is 15 m high. at the bottom her velocity is 9.7 m/s. approximately how much energy was "lost" due to friction?

an object of mass 60 kg is raised 12 m and then released. assuming no losses due to air resistance, what is its velocity two-thirds of the way down?

what is the work done by gravity when a wooden block of mass 2 kg slides 3 m down a slope inclined at 30 degrees?

a projectile is fired with an initial velocity of 60 m/s upward at an angle of 30 degree to the horizontal from a point 80m above a level plain. what horizontal distance will it cover before it strikes the plain?

Write the enantiomer of the following compound:

COOH

H OH

CH3

Assign R/S configuration to both the compounds.

1. Ruel is on his way to the grocery store riding his motorcycle. He started at rest in front of their house. He then travels ahead so that his distance from where he started is given by the equation: x(t) = (2.4 m/s²) t²-(0.120 m/ s²) t³

a. Calculate the average velocity of the motorcycle for the time interval t=0 sec to t=10 sec.

b. Determine the instantaneous velocity at t=0 sec and t=5 sec

A particle moves on a line with a constant acceleration of 4ft/second. Find its equation of motion if s=2ft and v=-ft/sec, when t=2sec
