Answer:
Approximately 
.
Explanation:
Note that the electric rate in this question is in the unit dollar-per-
, where 
is the energy to run an appliance of power 
for an hour.
Number of minutes for which the air conditioner is running in that day: 
. Apply unit conversion and ensure that this time is measured in hours (same as the unit of the electric rate.)
.
The power of this air conditioner is:
.
Thus, the energy that this air conditioner would consume would be:
.
At a rate of 
dollar-per-, the cost of that much energy would be approximately 
dollars (rounded to the nearest cent.)
Answer:
3 kg
Explanation:
Momentum before = momentum after
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
After jumping on the skateboard, the student and the skateboard have the same velocity, so v₁ = v₂.
m₁u₁ + m₂u₂ = (m₁ + m₂) v
(47.4 kg) (4.2 m/s) + m (0 m/s) = (47.4 kg + m) (3.95 m/s)
m = 3 kg
