Answer:
Explanation:
Let time taken by Jada in driving be t hour .
distance travelled by jada = 55 t
a )
Time of drive by destiny = t - 10 min
= t - .167 hour
distance of travel by destiny = 70 ( t - .167 )
Total distance = 45 miles
55 t + 70 ( t - .167 ) = 45
55t + 70 t - 11.69 = 45
125 t = 56.69
t = .453 hour = 27.21 minutes
b )
distance travelled by Destiny = 70 ( t - .167 )
70 ( .453 - .167 )
= 20.02 miles .
Answer:
<em>199,430Joules</em>
Explanation:
Gravitational potential energy is the energy possessed by a falling object due to virtue of its position.
gravitational potential energy = mass * acceleration due to gravity * height
gravitational potential energy = 55 * 9.8 * 370
gravitational potential energy = 539 * 370
gravitational potential energy = 199,430
<em>Hence the total change in the skier's gravitational potential energy is 199,430Joules</em>
