Power = Work done / time
Work done = Force * Distance
= 300 N * 1.5 m = 450 J
Power = 450 / 0.75 = 600 Watts.
Answer:
a) t = 4.5 s
, b) x = 81 m
Explanation:
a) For this problem we will use kinematic relationships
For the car
x = v₀ t + ½ a₁ t²
Since the car kicks from rest, the initial speed is zero
x = ½ a₁ t²
For the bus
v₂ = x / t
x = v₂ t
At the point where they are located it has the same position, so we can match the equation
½ a₁1 t² = v₂ t
½ a₁ t = v₂
t = 2 v₂ / a₁
Let's calculate
t = 2 18 /8.0
t = 4.5 s
b) to find the position
x = v₂ t
x = 18 4.5
x = 81 m
Its easy to create a visual and see major differences between data. If something takes up a large portion of the pie, its easy for you to tell just by looking at it
Answer:
Since the objects are all motionless after the collision, the final kinetic energy is also zero; the loss of kinetic energy is a maximum. Such a collision is said to be perfectly inelastic.
