Adriver in a car traveling at a speed of 26.8 m/s sees a deer 100 m away on the road. calculate the minimum constant acceleration that is necessary of the car to stop without hitting the deer (assuming the deer does not move). -4.20 m/s2 -1.75 m/s2 -2.89 m/s2 -3.59 m/s2

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
