Question

A body moving with a velocity of 40m/s is brought to rest in 5 seconds .the acceleration is,
(2 Points)

+8 m /s2

120m/s2

-8m/s2

-120m/s2​

Answer 1

Answer:

A motorboat traveling 6 m/s, North encounters a current traveling 3.8 m/s, South. What is the resultant velocity of the motorboat?

RES = 2.2 m/s north

A motorboat traveling 4 m/s, East encounters a current traveling 7.0 m/s, North. Determine the resultant.

RES = 8.06 m/s north east

Vector Components Any vector directed at an angle to the horizontal can be broken down into its two components.

Ax = A Cos theta

Ay = A Sin theta

A motorcycle stunt person traveling 37 m/s jumps off a ramp at an angle of 35 degrees to the horizontal. Determine the horizontal and vertical components of the motorcycles velocity.

AX = 30.31 m/s AY = 21.22 m/s
