zanele has a mass of 40kg and is sitting inside a 20kg cart .zanele's friends pull a cart with a force of 500N at an angle of 20°to the horizontal ,using a light rope .the cart experiences a frictional force of 300N .calculate the net horizontal force acting on the cart calculate the change in the carts momentum if zanele's friends apply the force for 10s calculate the net horizontal force acting on zanele how would the cart's final velocity be affected if angle between the 500N force and the horizontal is decreased ?explain your answer.

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
