If a man weighs 850N on the Earth, what would he weigh on Jupiter, where the free-fall acceleration is 25.9 m/s2?

Four acrobats of mass 67.0 kg, 68.0 kg, 62.0 kg, and 55.0 kg form a human tower, with each acrobat standing on the shoulders of another acrobat. The 67.0-kg acrobat is at the bottom of the tower. (a) What is the normal force acting on the 67.0-kg acrobat? (Enter the magnitude only.) 2469.6 ✔N (b) If the area of each of the 67.0-kg acrobat's shoes is 500 cm2, what average pressure (not including atmospheric pressure) does the column of acrobats exert on the floor? 53686.96 X Your response differs from the correct answer by more than 100%. Pa (c) Will the pressure be the same if a different acrobat is on the bottom? Pressure will be the same since the total mass of acrobats remains the same

A flea jumps by exerting a force of 1.10 x 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.660 x 10-6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.10 x 10-7 kg. Do not neglect the gravitational force. (Assume that the breeze blows in the +x-direction and that the +y-direction is up.) magnitude direction m/s² o counterclockwise from the +x-axis

An airplane has a mass of 3.13*10^4 kg and takes off under the influence of a comstant net force of 3.38 *10^4 N. what is the net force that acts on the 77.8 kg pilot ?

A net force of 20 N is acting on a falling object. The object experiences air resistance of 6.0 N. If acceleration due to gravity is 9.81 m/s^2 what is the mass of the object?

A powerful motorcycle can produce an acceleration of 3.50 m/s2 while traveling at 90.0 km/h. At that speed, the forces resisting motion, including friction and air resistance, total 400.0 N. (Air resistance is analogous to air friction. It always opposes the motion of an object.) What is the magnitude of the force that motorcycle exerts backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245 kg?

A certain cable of an elevator is designed to exert a force of 4.5 × 10^4 N. If the maximum acceleration that a loaded car can withstand is 3.5 m/s2, what is the combined mass of the car and its contents?

A box of mass 30.0 kg is acted on by a constant horizontal force, which moves the box from rest 15.0 m in 2.75 s. What is the magnitude of the force acting on the box?  (Ignore any frictional forces.)

A flea jumps by exerting a force of 1.80 x 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.700 × 10-6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.00 × 10-7 kg. Do not neglect the gravitational force. 19.0 m/s² at 2.23 degrees from vertical. 19.0 m/s² at 2.23 degrees from horizontal. 20.2 m/s² at 3.31 degrees from vertical. 20.2 m/s² at 3.31 degrees from horizontal. 10.2 m/s2 at 4.67 degrees from vertical. 10.2 m/s² at 4.67 degrees from horizontal.

An object of mass 13.0-kg subjected to a non-zero net force moves with an acceleration of (8.00î – 5.0oĵ) m/s². (a) Determine the magnitude and direction of the net force acting on it. magnitude direction ° counterclockwise from the +x axis (b) What acceleration would a 32.5-kg object have if the same net force is applied to it? Express your answer in vector form. a = m/s?
