<span>If I will be the judge, the passenger will not be injured by
suitcase came from the front of the bus because when the driver slammed the
break the inertia of the force must be moving forward. It impossible for a suit
case to move backwards, maybe the passenger was the one flying forward and hit
something </span>
Plug the values into the formula Vf=Vi+at:
Vf=Vi+at=8.33+3.5*6.8=32.13m/s
The correct answer is option C. i.e. 4%
<span>The total thickness of the stack of sheets is measured to be (0.80 ± 0.02) mm.
The maximum true thickness will be </span>(0.80 + 0.02) mm. = 1.00 mm
Ans, the maximum uncertainity will be <span> (0.20 + 0.02) mm = +/-0.04 mm
Thus, the four sheets true thickness will be </span>1.00 mm +/-0.04 mm
Thus, single sheet thickness will be 0.250 mm +/-0.01 mm
Thus, percentage error = (0.01/0.25) * 100 = 4%
Answer:
7m/s
Explanation:
Data obtained from the question include:
K.E (kinetic energy) = 4410J
m (mass) = 180kg
V (velocity) =?
Kinetic energy is the energy an object possess while in motion. It is represented mathematically as:
K.E = 1/2 mv^2
With the above formula, we obtained the velocity the car as follow:
K.E = 1/2mv^2
4410 = 1/2 x 180 x v^2
4410 = 90 x v^2
Divide both side by 90
v^2 = 4410/90
v^2 = 49
Take the square root of both side
v = √49
v = 7m/s
Therefore, the velocity of the car is 7m/s
