If air resistance in neglected, show (algebraically) that a ball thrown vertically upwards with a speed of vo will have the same speed, vo, when it comes back down to starting point.

Determine the maximum r-value of the polar equation r =3+3 cos 0

What causes the formation of ocean currents?

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
