Answer:
588 J
Explanation:
PE (potential energy) = (mass) x (gravity) x (height)
mass = 12 kg
gravity = 9.8m/s^2
height = 5 m
PE = (12) x (9.8) x (5) = 588 J (Joules)
Well the basic equation for velocity is v=d/t where d is distance and t is time. So v=2m/50s and the answer is v=0.04meter/second.
Answer:
A. 5 m/s
Explanation:
From the graph, for the first 2 seconds, the graph is a straight line meaning that the slope is a constant.
Average speed of an object is the rate of change of position. Here, the position of the object changes from 0 m to 10 m for a time interval of 2 seconds.
The change in position (
) and time interval (
) are given as:
Therefore, the average speed (
) is given as the ratio of the total change in position and the time interval for the change.
Hence, the average speed is 5 m/s.
Answer:
B
Explanation:
the balloon has a negative charge and the metal sphere has a positive charge
That completely depends on your speed and the trajectory (path) you choose.
The Apollo missions took about 3 days each way.
The New Horizons spacecraft passed the moon within a couple of hours after it was launched.
