Answer:
A=ACCELERATION = -4 m/s^2
B=DISTANCE= 72 m
Explanation:
Solving for the acceleration of the car
A= (10 m/s-30 m/s) / 5s
A= -20 m/s / 5s
A= -4 m/s^2
Solving for the distance traveled after the third second
D= v1 * t + 1/2at^2
D= 30 m/s * 3 s + -2m/s^2 * (3s)^2
D= 90 m + - 18 m
D = 72 m
Answer:
Kinetic energy = 127.89 Joules
Explanation:
Kinetic energy is calculated using the following rule:
KE = (1/2)*v* v^2
Where:
m is the mass = 145 g = 0.145 kg
v is the velocity = 42 m/sec
Substitute in the above equation to get the kinetic energy as follows:
KE = (0.5)(0.145)(42)^2
Kinetic energy = 127.89 Joules
Hope this helps :)
Yes. If an object would be vertical, it would most likely have potential energy due to gravity.

Explanation:
Answer:
3+2i ohm.
Explanation:
Here we have a complex number operation. According to Ohm's law V=I*R, so:
we need to remove the complex number on the denominator, so we have to multiply by its complement on both side
that gives us:
