What is true about the cannonball's motion? * Horizontal velocity is constant, and the vertical velocity is constant.

Horizontal velocity is increasing, and the vertical velocity is constant.

Horizontal velocity is decreasing, and the vertical velocity is constant.

Horizontal velocity is constant, and the vertical velocity is increasing.

Horizontal velocity is constant, and the vertical velocity is decreasing

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

What’s #16 asking me and how do i solve it?

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
