Answer:
the time taken for the automobile to travel the given distance is 80 mins.
Explanation:
Given;
speed of the automobile, v = 30 km/h
distance traveled by the automobile, x = 40 km
The time taken for the automobile to cover the given distance is calculated as;
time = distance / speed
time = 40 / 30
time = 1.3333 hours = 1.3333 hr x 60mins/hr = 80 mins
Therefore, the time taken for the automobile to travel the given distance is 80 mins.
Answer:
PE = 882 J
Explanation:
Through the International System we know that the gravity of the earth is 9.8 m/s², so...
Data:
- m = 45 kg
- g = 9.8 m/s²
- h = 2 m
- PE = ?
Formula:
Replace and solve:
The potential energy of the sled is <u>882 Joules</u>.
