A red object moves at a velocity of 11.9760479 m/s. A blue object moves at a...
2. An observer S sees a flash of red light 1200 m from his position and a flash of blue light straight line. He measures the time interval between 720 m closer to him and on the same the occurrences of the flashes to be 5 microseconds, the red flash occurring first. a. What is the relative velocity v of a second observer S' who would record these flashes as occurring at the same place? b. From the point of...
don't know if I'm correct in thinking that red gives green, then vice versa... ans blue gives yellow, then vice versa.... ?? We see images because the rods and cones are generating nerve impulses for transmission to the brain. Occasionally the is one in which the bright parts of the object remain bright and the dark parts remain dark. In a negative afterimage Afterimages brain retains an image even after the impulses have stopped. These images are called afterimages. A...
3) Object A (m 5 kg) moving at 1 m/s moves toward a stationary object B (m 3 kg). At 1-0 s, they collide in I dimension. The force between the objects as a function of time is: IN 2.0 1.s 10 05 a) Att 4 s, the velocity of the object B is: (I pt) b) Att-4s, the velocity of the object A is: (1 pt)
an object moves in the +x direction at a speed of 48 m/s. As it passes through the origin, it starts to experience a constant acceleration of 4.0 m/s^2 in the -x direction. a. how much time elapses before the object returns to the origin? b. what is the magnitude of the velocity of the object when it returns to the origin? c. what is the direction of the velocity of the object when it returns to the origin? -x...
An object moves with constant acceleration. At t = 2.50 s, the position of the object is x = 2.00 m and its velocity is v = 4.50 m/s. At t = 7.00 s, v = -12.0 m/s. Find: (a) the position and the velocity at t = 0; (b) the average speed from 2.50 s to 7.00 s, and (c) the average velocity from 2.50 s to 7.00 s.
A 5.71 kg particle-like object moves in a plane with velocity components vx = 16.9 m/s and vy = 51.5 m/s as it passes through the point with (x, y) coordinates of (9.95, -7.85) m. Just then, in unit-vector notation, what is its angular momentum relative to (a) the origin and (b) the point (-6.87, -6.87) m?
8) An object, initially moving with a velocity of 2.0 m is, moves in a straight line with constant acceleration. After traveling a displacement of 5.0 m, it attains a velocity of 3.0 m is. Its acceleration, in m/s2, is: (Please show all work and formula(s) used)
The figure(Figure 1) shows the velocity graph of a 2.7kg object as it moves along the x-axis. A) What is the net force acting on this object at t= 1 s? B) At 4 s? C) At 7 s? The figure(Figure 1) shows the velocity graph of a 2.7kg object as it moves along the x - axis. A) What is the net force acting on this object at t= 1 s? B) At 4 s? C) At 7 s?
(1) Observer S (at x 0) sees a flash of red light at XR 1200 m from her position and a flash of blue light at x,-480 m on the same straight line. She measures the time interval between the flashes to be 5 us, with the blue flash occurring first (that is, ted ue 5 Hs.) What is the velocity v of observer S' who records the flashes as occurring at the same place, that is, who measures Ax...
Someone is travelling at a velocity of 2.8e8 m/s away from a stationary observer and throws an object foward with a velocity of 2.1e8 m/s (relative to the student). find the velocity of the object with respect to the stationary observer.
