Question 48

An oceanographic research team tests two moving underwater instruments, A and B. The mass and speed of B can each be set to 1, 2 or 4 times the corresponding value for A. The team wants B to have eight times the kinetic energy of A.

Which combination of mass and speed settings for B achieves this?

[1]
A

Mass twice that of A and speed twice that of A

B

Mass twice that of A and speed four times that of A

C

Mass unchanged and speed four times that of A

D

Mass four times that of A and speed twice that of A
