A truck starts from rest and rolls down a hill with a constant acceleration. It travels a distance of 400 m in 20. Find its acceleration. Find the force acting on it if its mass is 7 tonnes.

Answer»

ata: Mass of STONE(m)=7000 KG DISTANCE(S)=400 meter Time(t)=20 second 1) We have to FIND the acceleration of the truck So from the equation of motion S= ut+1/2      at 2 , where u=0 S=1/2aX t2          a=    2×S/t2   =   2×400/20×20    =2m/ sec 2     2) Force acting on truck So, from newton's 2 nd  law of motion F  =ma=7000×2=14000N=14kN             HOPE THIS WOULD HELP U!!!!!!                MARK IT AS BRAINLIEST IF U WANT TOO!!!!! ​ m ​
