Question
A spherical ball weighing 2 kg is dropped from a height of 4.9 m onto an immovable rigid block as shown in the figure. If the collision is perfectly elastic, what is the momentum vector of the ball (in kg m/s) just after impact?
Take the acceleration due to gravity to be π = 9.8 m/sΒ² . Options have been rounded off to one decimal place.
Options :
19.6 πΜ
19.6 πΜ
17.0 πΜ+ 9.8 πΜ
9.8 πΜ+ 17.0 πΜ
