If vx = 0.40 meters/second and vy = 3.00 meters/second, what is the value of θ?

Which of the following represents an upside-down image?

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2 . how much is the spring compressed x from its natural length?
