+28 A constant force is applied to an object, causing the object to accelerate at 10 m/s2 .
Part A
What will the acceleration be if the force is halved?
Express your answer using two significant figures.
a = ________________ m/s2
Part B
What will the acceleration be if the object's mass is halved?
Express your answer using two significant figures.
a = __________________m/s2
Part C
What will the acceleration be if the force and the object's mass are both halved?
Express your answer using two significant figures.
a = __________________ m/s2
Part D
What will the acceleration be if the force is halved and the object's mass is doubled?
Express your answer using two significant figures.
a = ______________ m/s2
+9673 Still my shaky knowledges, I apologize again for this.
Part A:
Force is halved, Mass remains unchanged, Acceleration is halved.
So that a = 5 m/s2
Part B:
Force is constant, mass is halved, acceleration is doubled.
Therefore a = 20 m/s2
Part C;
Force is halved, Mass is halved, therefore acceleration is constant.
Therefore a = 10 m/s2
Part D:
Force is halved, Mass is doubled, Acceleration is halved twice <---- which is 1/4.
Therefore a = 5 x 1/4 = 1 1/4 m/s^2
