A man is pulling a sled with a box. The mass of the sled is 7.0kg while the mass of the box is 8.0kg. The frictional force between the ground and the sled is 10N. The man exerts a force at an angle of 30 degree to the vertical and the sled and the box has an acceleration of 1.5m/s^2
(1)Calculate the force that man exerts on the sled.
(2)Calculate the frictional force that the sled exerts on the box and the direction of the frictional force.
(3)if now the man walked up a slope of 10 degree. Calculate the force exerted assume all other conditions are unchanged (friction and acceleration and)
