If an object moves with constant (non-zero) acceleration, then which, if any, of the following statements about its motion is/are true?
the position may be increasing or decreasing.
a: true b: false

the acceleration may be increasing or decreasing.
a: true b: false

the velocity may continually change by varying amounts depending on the speed.
a: true b: false

the speed must continually change by the same amount during each equivalent unit of time.
a: true b: false

the magnitude of the velocity, or speed, also could be constant. a. true. b. false

Arowboat passenger uses an oar to push the boat off the dock by exerting a force of 40n for 3.0s. what impulse acts on the boat.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
