- A 3 kg particle is moving with an initial velocity of 20 m/s to the right when it explodes into two fragments. Immediately after the explosion, which occurs at the origin of the coordinate system, the velocity of fragment A is observed to be 60 m/s and the fragments are traveling in the direction shown. Answer: A) what is the mass of fragment A; B) what is the speed of fragment B.arrow_forwardHi, could you help me, please?arrow_forwardPart A Ball A has a mass of 3 kg and is moving with a velocity of (vA)ı = 8 m/s when it makes a direct collision with ball B, which has a mass of 2.5 kg and is moving with a velocity of (vB)1 = 5 m/s. Suppose that e = 0.8. Neglect the size of the balls. (Figure 1) Determine the velocity of A just after the collision measured to the right. Express your answer to three significant figures and include the appropriate units.

- Q4 2. A ball is launched with an initial velocity of Vo = 4.5 m/s from point P at a 30° sloped surface with an angle of 0. The ball lands at point B, which is 0.6 m higher than point A. Determine the launch angle 0 of the ball, the impact velocity at B (vB), the angle vg makes with the horizontal and the duration of the flight. Also determine the radius of curvature of the path and the rate of change of the speed of the ball at point C, where its trajectory makes an angle of 60° with the negative x-axis. g 9.81 m/s-.arrow_forwardPlease answer correctly and quickly, please.arrow_forwardA ball A is projected from O with an initial velocity Vo = 700 cm/s in a direction 37o above the horizontal. A ball B300 cm from O on a line 37o above the horizontal is released from rest at the instant ball A starts. (a) How far willball B have fallen when it is hit by ball A? (b) In what direction is ball A moving when it hits ball B?arrow_forward
