Answer:
dC = 72m < dA = 80m < dB = 90m
Explanation:
In order to calculate the distance traveled by each mobile, you use the following formula:
(1)
d: distance traveled
v: speed of the car
t: time of the motion
You replace the values of v and t for each mobile:
mobile A:
mobile B:
mobile C:
Then, you obtain that he distances traveled by the mobiles show:
dC = 72m < dA = 80m < dB = 90m
Answer:
A. 3.3 m
Explanation:
Here, we have to use conservation of energy principle.
When the ball is at maximum height, the instantaneous velocity at that point is 0 m/s. So, the kinetic energy of the ball is also 0 at the maximum height. Thus, at maximum height, the energy possessed by the ball is gravitational potential energy only.
Now, when the ball reaches the ground, all the gravitational potential energy changes into kinetic energy because of the conservation of energy.
Therefore, the energy transformation can be given as:
Decrease in potential energy = Increase in Kinetic energy
Decrease in potential energy is given as:
Increase in kinetic energy is given as:
Therefore,
Now, plug in 8 for , 9.8 for
and solve for height
. This gives,
Therefore, the maximum height reached by the ball is 3.3 m.
