Answer:
B. 3 m/s
Explanation:
We can solve the problem by using the law of conservation of momentum; in fact, the total momentum before and after the collision must be conserved. So we can write:
where:
m1 = 150 kg is the mass of spaceship 1
m2 = 150 kg is the mass of spaceship 2
u1 = 0 m/s is the initial velocity of spaceship 1
u2 = 6 m/s is the initial velocity of spaceship 2
v is the velocity of the two ships after they collide and stick together
Solving for v, we find:
Answer:
false

What does Michaelis believe caused Myrtle to run? He thinks she was running away from Wilson. She thought Tom was in the yellow car because she had seen him in it earlier. She was running towards Tom
Answer:
Approximately (assuming that the car is moving on level ground, and that there is no friction to hinder the motion of the car.)
Explanation:
Formula for the kinetic energy, , of an object of travelling at velocity :
.
Let and denote the velocity of this car before and after the acceleration.
Kinetic energy of this car before the acceleration:
.
Kinetic energy of this car after the acceleration:
.
Assume that this car was travelling on level ground. Also assume that there is no friction to hinder the motion of this car. The work of the engine of this car would be equal to the amount of that the car has gained:
.
