Answer:

51. A 5.20-N force is applied to a 1.05-kg object to accelerate it rightwards. The object encounters 3.29-N of friction. Determine the acceleration of the object. (Neglect air resistance.) PSYW

Answer: 1.82 m/s/s, right

Upon neglecting air resistance, there are four forces acting upon the object. The up and down forces balance each other. The acceleration is rightward since the rightward applied force is greater than the leftward friction force. The horizontal forces can be summed as vectors in order to determine the net force.

Answer:A

Explanation: because the gravitational pull only allows in space, the lift is always there, and the are not forces balanced because the gravity is currently overtaking the other fundamental forces.
