Answer:
3.9m/s² is the acceleration
Answer:
When the body is kept at the surface there height of the stone is equal to zero. hence, if the height of the stone is zero then Potential energy is equal to zer
This means that the horizontal force is 750sin(25°). To be able to move the truck, force applied must be greater than static friction, which equals to its coefficient (0.77) x normal contact force (= weight)
Hence, 750sin(25°) = 0.77mg. m = 750sin(25°)/(0.77g)
