A pumpkin cannon-retrofitted to launch wedding cakes-is aimed at 40° above the horizontal and a wedding cake of mass 4.5 kg is fired across a flat field at a velocity of 35 m/s.
What is the length of time the cake is in the air?

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
