DO NOT SKIP!! Let’s see who’s smart enough to work out both problems if u get it correct I’ll mark u as BRAINLIEST

16 is Potential energy and 411.6 Joules, 17 is Kinetic energy 896,000

Step-by-step explanation:

PE=mgh

2 kg(9.8m/sec^2) 21m= 411.6J

KE=1/2mv^2= 1/2(1120kg)(40m/s)^2= 896,000J

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
