A vehicle collides with a rain gate barrier when traveling at 27.75m/s and is brought to rest in 0.075s. if the mass of vehicle and the occupant is 1000kg .calculate the average force on the vehicle .the driver used his seat belt which restricted his movement through a distance of 0.25m relative ti the seat. what was the average force exerted by the belt on the driver if the driver's mass is 100kg.​

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
