A displacement vector in the xy plane is 20 m long and directed at angle θ= 30° in figure given below:

Determine the y component of the vector.

Four objects move with the velocity-versus-time graphs shown. Which

object has the largest displacement between

Every

minute, 268 C of charge flows through this cross section of the wire.

What

is wire’s current?

Mom and Dad have tied a

rope to Matthew’s sled and are momentarily pulling him through the snow. Dad is

pulling with force A and Mom with force B.

A: 54 N at 65° north of east

B: 130 N at 22° south of east

Determine the acceleration

that these momentary forces would create for a 39-kg sled and child (assuming

negligible friction).

Which of the three right -hand charges experience the largest

force?

Which of the following values is a

vector

quantity?

A car moving at a constant velocity of 20m/s, east for 5 seconds has an acceleration of ____ m/s²

A car suspension spring has an equilibrium length of
