answer
60.1667
explanation
there are four main kinematic formulas that we use in physics
= final velocity
= initial velocity
a = acceleration
t = time
x = displacement
we use an equation based on what information we have
in this question, we have initial velocity (0), final velocity, (38), displacement (12), and we want to find acceleration
so we use the equation that includes
which is this equation
rearrange to solve for a
plug in values
Answer:
because all power is being stored in the battery instead of draining the battery getting a result of a smaller and smaller voltage put through the circuit
Explanation:
say the battery is 1.5 volts, in a circuit it is slowly decreasing the power output of 1.5 volts to 0 volts by using the power within the battery when you have the battery disconnected the voltage will remain the same as which you left it
Answer:water is more dense
Explanation:
Answer:
SA = 18.6 * t + 186 total distance traveled by A in time t
SB = 24.4 t total distance car B must travel to catch car A
SA - SB = 0 = 18.6 t + 186 = 24.4 t
(24.4 - 18.6) t = 186
t = 186 m / 5.8 m/s = 32 s
Check 18.6 * 32 + 186 = 781 m
24.4 * 32 = 781 m
Given :
A tourist drops (from rest) a ping pong ball from the top of the tower, which has a height of 174 meters.
To Find :
How long does it take for the ping pong ball to hit the ground ?
Solution :
We know, equation of motion of object doing free fall is :
....1)
Here, g = 9.8 m/s² ( acceleration due to gravity )
Also, u = 0 m/s ( its free fall )
Putting these values in equation 1), we get :
Therefore, ball will take 5.96 s to hit the ground.
