QUESTION 10
Two people on ice skates stand face to face and then push each other away. If their masses are 45 and 75 kg, what is the ratio of their speeds immediately afterward?
|
Speed of the 45 kg skater is 1.7 times the speed of the 75 kg skater |
||
|
Speed of the 45 kg skater is 1.2 times the speed of the 75 kg skater |
||
|
Speed of the 45 kg skater is 0.6 times the speed of the 75 kg skater |
||
|
Speed of the 45 kg skater is 2.0 times the speed of the 75 kg skater |
Homework Answers
By the law of conservation of momentum
m1v1 = m2v2
Here m1 = 45 kg and m2 = 75 kg
45 v1 = 75 v2
So Speed of the 45 kg skater is 1.7 times the speed of the 75 kg skater

Two ice skaters stand facing each other at rest on a frozen pond. They push off against one another and the 48-kg skater acquires a speed of 0.69 m/s. If the other skater acquires a speed of 0.87 m/s, what is her mass? ____kg

Two ice skaters have masses m1 and m2 and are initially stationary. Their skates are identical. They push against one another, as in Figure 7.10, and move in opposite directions with different speeds. While they are pushing against each other, any kinetic frictional forces acting on their skates can be ignored. However, once the skaters separate, kinetic frictional forces eventually bring them to a halt. As they glide to a halt, the magnitudes of their accelerations are equal, and skater...

Two ice skaters, with masses of 73kg and 55kg , stand facing each other on a 18-m-wide frozen river. The skaters push off against each other, glide backward straight toward the river's edges, and reach the edges at exactly the same time. how far did the 73kg skater glide?

Three ice skaters meet at the center of a rink and each stand at rest facing the center, within arm’s reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass mA = 80.0 kg moves in the negative y-direction at 3.50 m/s and skater B with mass mB = 75.0 kg moves in the negative x-direction at 4.00 m/s. Find the x-...

Two ice skaters stand together as illustrated in Figure (a) below. They "push off" and travel directly away from each other, the boy with a velocity of v = 0.74 m/s to the left. If the boy weighs 711 N and the girl weighs 473 N, what is the girl's velocity after they push off? (Consider the ice to be frictionless. Enter the magnitude only.)Two ice skaters stand together as illustrated in Figure (a) below. They "push off" and travel...

Two ice-skaters, whose masses are 45 kg and 75 kg, hold hands and rotate about a vertical axis that passes between them, making one revolution in 2 s. Their centers of mass are separated by 1.7 m, and their center of mass is stationary. Model each skater as a point particle. (a) Find the angular momentum of the system about it's center of mass. J·s (b) Find the total kinetic energy of the system.
