Physics: Force Questions

[From: ] [author: ] [Date: 11-06-22] [Hit: ]
c. What is the normal force acting on this object if the object is on the ground?d. If there were actually two forces acting on the object during its acceleration, and one of those was a frictional force of 10N to the left, what force was pushing it to the right?......
1. If a 10kg object is accelerating to the right across the ground at 5m/s squared.

a. What is the net force acting on the object?
b. What is the gravitational force acting on this object?
c. What is the normal force acting on this object if the object is on the ground?
d. If there were actually two forces acting on the object during it's acceleration, and one of those was a frictional force of 10N to the left, what force was pushing it to the right?
e. What is the friction coefficient between the two surfaces?

Sorry that the question is so long but I could really use the help. Thanks!

-
a) Force = (mass x acceleration) = 10 x 5, = 50N.
b) Gravitational force is (9.8 x 10kg) = 98N. down to the ground.
c) Normal force is 98N. also, acting up from the ground.
d) (50 + 10) = 60N. acting right.
e) Friction force is 10N. Applied force is 60N. Coefficient = (10/60) = 0.167.
