Krystal heard the meowing and came to help him down. She decided this was a good opportunity to calculate the tension force Charlie exerted on the curtains. She placed him on a scale and used his mass to calculate the tension force on the curtains. If the cat caused 37N of tension on the curtain, what is Charlie's mass?

Round your answer to 2 significant figures.A 284N crate resting on a plane inclined 37-degrees with the horizontal requires a 23.9N force to bring it down to 6.4m from its initial position. The force is applied 55-degrees with respect to the horizontal. Neglecting friction between the crate and plane, determine the time (in seconds) that the crate had travelled a distance of 6.4m. Answer in two decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.An 18.5 lb box is placed on the ground. What force (in lb) does the ground exert on the box? (magnitude and direction). A cord is attached to the box and run through a pulley directly above the box, so that the cord is vertical. The free end of the cord is then connected to a hanging weight. Calculate the force exerted by the ground on the box (in lb), if the hanging weight is 12.0 lb (magnitude and direction) A 29.0 lb weight is substituted for the 12.0 lb weight. Calculate the new force (in lb) exerted by the floor on the box (magnitude and direction).
