Assume that the projectile motion shown in Figure 6-1 is ideal with no friction. For that assumption, choose the correct statements about the motion in 1 and 2 below.

1. (a) The value of υ_x is always positive and decreases very slightly with time. (b) The value of υ_x changes from positive to negative with time. (c) The value of υ_x is always negative and increases very slightly with time. (d) The value of υ_x is always positive and is constant with time. (e) The value of υ_x changes from negative to positive with time.

Expert Solution & Answer

To determine

The correct statement for the projectile motion with no friction.

Answer to Problem 1PLA

Option (d) the value of vx is always positive and is constant with time.

Explanation of Solution

According to Newton’s first law of motion, a moving object continues to move in the same direction with constant velocity unless an unbalance force is acted upon it.

Assuming there is no friction in the projectile motion in Figure 6-1. No horizontal force is acting on the object. Therefore, the horizontal velocity of the object will be constant. And as the object is moving in positive x-direction, the horizontal velocity is positive.

Conclusion:

(a) The projective motion is ideal with no friction and there are no horizontal force acting on the object. Therefore the velocity does not decrease with time. Option (a) is incorrect.
(b) The horizontal velocity does not change from positive to negative with time. Option (b) is incorrect.
(c) The vx is not negative and there is no horizontal acceleration. Option (c) is incorrect.
(d) No horizontal force is acting on the object and the object is moving in positive x-direction. Option (d) is correct.
(e) The horizontal velocity does not change from negative to positive with time. Option (e) is incorrect
