If M = 2m and m is released from rest at h above the ground, find the speed of the mass m just before touching the ground.

Thor stands on the top of stark tower 425 m adn fights his brother loki using mjolnir his hammer. if his hammer has a mass equal to 300 billion elephants  cal it 4.5*10^15 kg what i the gaviation potential energy in J of jjolnir relative to the ground? use scientific notation to enter you answer. B. Loki tricks thor into dropping Mjolnir off stark tower. when the hammer has fallen one third of the way down the tower what is its kinetic energy in J? Hint you could find the speed then calculate the kinetic energy but there's an easier way...

Pls help ASAP.

please help with these. Thanks bartleby An object moving at 33 m/s [N] is accelerated at 7 m/s2 [W] for 8 seconds. What is the speed of the object after 8 seconds?   Question options:   23 m/s   45 m/s   65 m/s   89 m/s An object moving at 4.0 m/s [E] accelerates uniformly so that 2.0 s later, it is moving at 3.0 m/s [N]. What is the magnitude of the object's displacement over this time interval?   Question options:   5.0 m   7.0 m   10 m   14 m An object moving at 4.0 m/s [E] accelerates uniformly so that 2.0 s later, it is moving at 3.0 m/s [N]. What is the magnitude of the object's acceleration?   Question options:   0.50 m/s2   2.5 m/s2   zero   It cannot be determined.

One newly discovered light particle has a mass of m and property q. Suppose it moves within the vicinity of an extremely heavy (fixed in place) particle with a property Q and mass M. When the light particle is xi distance from the heavy particle, it is moving directly away from the heavy particle with a speed of vi. a) What is the lighter particle's speed when it is xf away from the heavy particle? Consider a new expression for gravitation potential energy as: , where A is a constant, m1 and m2 are the masses of the two objects, and r is the distance between them. Moreover, the new particle has an additional interaction with the heavy particle through the following force expression   where  is a constant that is read as epsilon subscript 0, q and Q are their new properties, r  is the distance between the new particle and the heavy particle. Solution: We may solve this using two approaches. One involves the Newton's Laws and the other involving Work-Energy theorem. To avoid the…
