No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.
Answer:
average force is 138900 N
Explanation:
given data
speed = 50 km/h = 13.89 m/s
mass = 1500 kg
time = 0.15 s
to find out
average force
solution
we know initial velocity of car is positive
we will apply here equation to find force that is
Force x change in time that is equal to mass x change in speed ................1
so put here all value of mass, time and velocity in equation 1
Force x 0.15 = 1500 x ( -13.89)
force = 138900 N
so average force is 138900 N
Answer:
It's weight would decrease over time.
Explanation:
The cold coke is going to stabilise in the room temperature. This causes the coke to heat up to room temperature. When the coke heats up, some molecules acquire enough kinetic energy that the evaporate. The evaporation of the molecules causes a decrease in weight.
Hope it helped!
<span>The condition alone that is necessary so that the final kinetic energy of the system is zero after the collision is that the
objects must have momenta with the same magnitude but opposite directions.</span>
