Looking at the two motion graphs, in which direction is the object moving faster?

Physics
1 answer:
SSSSS [86.1K]3 years ago
3 0

The answer is A) In the X-direction.

This is the case because, when you are asked about speed on a motion graph, the steeper the line gets, the faster it is going. In the first motion graph "Distance vs Time (X-direction)" the line is getting steeper, so that means it is going faster than the line depicted on the second graph.

Hi =D
   The answer is D. This is how i figured it out. pV = n R T => if pressure is constant => p = n R T / V = const. => p / n R = T/ V = const. => T / V = const. T1 = 333 K T2 = 533 K V1 = 0.2 m3 T1 / V1 = T2 / V2 => V2 = V1 x T2 / V2 = 0.2 x 533 / 333 = 0.32 m^3.
   Hope this is what your looking for.

vodka [1.7K]

Answer:

51.96 m/s^-1

Explanation:

a) see the attachment

b) As we know the velocity of the projectile has two component, horizontal velocity v_ox. and vertical velocity v_oy as shown in the figure. At the highest point of the trajectory, the projectile has only horizontal velocity and vertical velocity is zero. Therefore at the highest point of the trajectory, the velocity of the projectile will be  

v_ox=v_o*cosФ

       =60*cos (30)

      = 51.96 m/s^-1
