A 23 kg suitcase is being pulled with a constant speed by a handle that is at an angle of 25° above the horizontal. If the normal force exerted on the suitcase is 155 N, what is the force F applied to the handle?

and..

A paleontologists estimate that if a Tyrannosaurus rex were to trip and fall, it would have experienced an upward normal force of approximately 261,500 N acting on its torso when it hit the ground. Assume the torso has a mass of 3720 kg.
and i foudn that the magnitude is 60.4857 when it comes to rest

(b) Assuming the torso is in free fall for a distance 1.51 m as it falls to the ground, how much time is required for the torso to come to rest once it contacts the ground?
