a.
To Sketch: The situation of skaters when they hold each other & loose contact with the help of sketch.
a.
Explanation of Solution
Given:
The mass of Diego,
The mass of Keshia,
The sketch of the situation is given below :
The before and after parameter:
Conclusion:
The initial velocity of each skater is zero & the mass will be same before & after the event .
b.
The ratio of velocities just after the hand loose contact.
b.
Answer to Problem 74A
The ratio of velocities just after the hand loose contact is
Explanation of Solution
Given:
The mass of Diego,
The mass of Keshia,
Formula Used:
The linear momentum is conserved .
Calculation:
As per the given problem
Substitute these values in the formula
The negative sign shows that the direction of velocities is different .
Conclusion:
The ratio of velocities just after the hand loose contact is -1.5 here negative sign denotes the opposite direction.
c.
The speed of which skater is greater.
c.
Explanation of Solution
As the weight of Diego is greater than the Keshia so, Keshia has greater speed due to less weight.
Conclusion:
The Keshia has greater speed.
d.
The skater who pushed harder.
d.
Explanation of Solution
Both skaters pushed each other with equal & opposite forces as per
Conclusion:
Both will experience same force (pushed ).
