In one hand you hold a .12-kg apple, in the other hand a .20-kg orange. The apple and orange are separated by .75 m. What is the magnitude of the force of gravity that (a) the orange exerts on the apple? (b) the apple exerts on the orange?
22. The main difference between speed and velocity involves A. direction. B. weight. C. distance. D. gravity.
20. The model of the universe that suggests that the sun is the center of the universe was first brought by A. Copernicus. B. Brahe. C. Ptolemy. D. Kepler.
A car Rounds a curve while maintaining a constant speed. Is there a net force on the car as it rounds the curve? A: it depends on the sharpness of the curve and speed of the car. B: no - it's speed is constant C: yes
if you push a chair across the floor at a constant velocity how dose the force of friction compare with the force you exert?
Pls Help! A string is tied to a 4.4 kg block and 120g hanging bucket. Students add 20g washers one at a time to the bucket. The student are unaware that the coefficient of static friction for the block on the table is 0.42. A) what is the maximum force of static friction for the block? Answer: 18.11N B) how many washers can the students add to the bucket without moving the block? Answer: 86 C) the coefficient on kinetic friction is 0.34. Calculate the acceleration of the block when the final washer is added to the bucket and the objects start to move... The diagram is the block on the table that is sitting horizontally on a table with a pulley holding the bucket vertically with one string. The block and the bucket are tied with one string. I jus didn't get c)
A ball pushed with a force of 13.5 N accelerates at 6.5 m/s^2 to the right. What is the mass of the ball?
What weight of water is displaced by a 100-ton floating ship? The answer must be in SI units. This part is driving me insane, because no matter how much I search for its possible solution, I can't find it.
A car (m=1700 kg) is parked in a road that rises 15 degrees above the horizontal. What are the magnitudes of a. the normal force b. the static frictional force that the ground exerts on the tires?
Two trunks sit side by side on the floor. The large trunk (52kg) is to the left of the smaller trunk (34kg). A person pushes on the larger trunk horizontally toward the right. The coefficient of static friction between the trunks and the floor is 0.35. a) determine the magnitude of the maximum force the person can exert without moving either trunk. *I got 290N. b) Calculate the force the larger trunk exerts on the smaller trunk. Update : c) Would either answer change if the person pushed in the opposite direction on the smaller trunk. Explain your reasoning.
