Initially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in the figure below. They are released from rest simultaneously and collide elastically in the trough of the track. If m2 = 9m1, m1 = 0.049 kg, and h = 0.66 m, what is the velocity of each ball after the collision? (Assume the balls slide but do not roll. Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) V1f = m/s? V2f = m/s?
Raul kicked a soccer ball. The ball approached Raul's foot with a momentum of magnitude pi = 11.2 kg m/s. The ball left his foot with a momentum of magnitude pf = 14.2 kg m/s. The orientation of the initial and final momentum vectors is shown in the diagram above, with the smallest angle between the incoming and outgoing vectors being θ = 58 degrees, as shown. The ball was in contact with Raul's foot for an amount of time equal to 7.3 ms (that says milliseconds). Assuming all other forces are negligible by comparison, calculate the magnitude of the average force (in newtons) that Raul exerted on the ball during those 7.3 milliseconds.
Far in space, where gravity is negligible, a 465 kgkg rocket traveling at 75.0 m/sm/s fires its engines. The figure (Figure 1) shows the thrust force as a function of time. The mass lost by the rocket during these 30 ss is negligible. What impulse does the engine impart to the rocket? Express your answer as an integer and include the appropriate units. At what time does the rocket reach its maximum speed? Express your answer to three significant figures and include the appropriate units.
********PLEASE ONLY ANSWER PART D AND E******* Starting with an initial speed of 5.38 m/s at a height of 0.380 m, a 1.87-kg ball swings downward and strikes a 5.13-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 1.87-kg ball just before impact. This value is 6.03 m/s (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 1.87-kg ball just after the collision. This value is -2.01 m/s (c) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 5.13-kg ball just after the collision. This value is 3.22 m/s (d) How high does the 1.87-kg ball swing after the collision, ignoring air resistance? (e) How high does the 5.13-kg ball swing after the collision, ignoring air resistance? I just need d and e answered please! Thank you.
