The toddler weighs 12.5 kg.
In-depth explanation:
The formula for gravitational potential energy is Ep=mgh where;
Ep=gravitational potential energy
m=mass of an object
g=gravitational field strength
h=height in meters
Given that; h= 1.5m, Ep=187.5J, g=10 N/kg then finding m;
Ep=mgh
187.5=m*10*1.5
187.5=15m
187.5/15 =15m/15
m=12.5 kg

The equivalence exists because tenths represent one-tenth of a whole. Having 20 tenths means multiplying 20 by 1/10, resulting in 20/10, which simplifies to 2 wholes. Conversely, expressing 2 as 20 tenths yields the same amount.
Answer:

Step-by-step explanation:
First, we determine v and a as:


Subsequently, we compute the cross product and substitute it into the formula for k
a(t) X v(t) = (0,0,2)
| a(t) X v(t) | = 2

Thus, we conclude
