Answer:
Because work can be defined as force time distance, we can also use the following equation
Solution
P=power (w or ft-lbf/s)
F=force (N or lbf)
D=distance (m or ft)
T=time (sec)
One horsepower is equivalent to 550 ft-lbf/s and 745.7 watts.
B, because people buy cars everyday
Milky way doesnt have planets oribting arount the sun like our solarsystem.
Answer:
12.65 m/s
Explanation:
When friction is ignored, if the car travels from 18m hill to the bottom of the hill, afterwards it travels up to a 10m hill, then overall it has traveled a distance of 18 - 10 = 8 m vertically.
If the car starts from rest, then its potential energy is converted to kinetic energy:
where m is the car mass and h is the vertical distance traveled, v is the car velocity at 10m hill
Let g = 10m/s^2. We can cancel m from both sides of the equation:
Answer:
1421 seconds or 23.67 minutes
Explanation:
Q = Heat = 1200 W
c = Specific heat of human body = 3480 J/kgK
= Change in temperature = (44-37)°C
t = Time taken
The time student jogs before irreversible body damage occurs is 1421 seconds or 23.67 minutes
