a body moves on frictionless surface forward along a straight line it uses q velocity 48km/hr for ⅓ of the total path and it's motion is continued so that it uses 52 km/hr for ⅔ of the total path then calculate the average velocity of the body

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
