Answer:
At 4 hours both options will be $16.00
Step-by-step explanation:
Basketball has a mass of 0.1kg
m = 0.1 kg
The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero
a = 0m/s²
The constant speed is 6m/s
v = 6m/s
So, force to keep it moving with this constant speed can be calculated using Newton second law of motion
F = ma
F = m × 0
F = 0N
So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
Let
c-----------> represent the cost of each shirt without discount
t-----------> <span>total cost for the three shirts after the discount
d----------> discount
we know that
d=3c*0.20
t=3c-d-------------> 3c-[3c*0.20]--------> 3c*[1-0.20]=3c*(0.80)
the answer is 3c*(0.80)</span>
