A child is pulling a 14.4 kg wagon by the handle. This 38.3 N pull force is applied through the handle and acts on the wagon at an angle of 35° above horizontal. Calculate the normal force on...

A child is pulling a wagon by the handle. This force is applied through the handle and acts on the wagon at an angle of 35° above horizontal. If the normal force on the wagon is 85.6N and the...

This question is based on the same scenario; however, the numbers are different. A child is pulling a 5.2 kg wagon by the handle with a 49.7 N force. This force is applied through the...

A child is pulling a 11.4 kg wagon by the handle. This 27.4 N pull force is applied through the handle and acts on the wagon at an angle of 35° above horizontal. Calculate the normal force on...

A child is pulling a wagon by the handle. This force is applied through the handle and acts on the wagon at an angle of 35° above horizontal. If the normal force on the wagon is 76.9N and the...

A child is pulling a 6.8 kg wagon by the handle with a 64 N force. This force is applied through the handle and acts on the wagon at an angle of 35° above horizontal. If the friction force on the...

Three forces acting on an object are given by 1 = ( - 1.70 ) N, 2 = ( - 4.70 + 3.10 ) N, and 3 = ( 47.0 + 42.0 ) N. The object experiences an acceleration of magnitude 3.50 m/s2...

The Gravitation potential difference between the surface of planet and a point 20m above is 16 J/kg. Calculae the work done in moving a 4 kg mass by 8m on a slope of 60degree from the horizontal....

A 3.00 kg block starts from rest at the top of a 30° incline and slides a distance of 1.90 m down the incline in 1.40 s.(a) Find the magnitude of the acceleration of the block. m/s2 (b)...

On May 20, 1999, Robbie Knieval easily cleared a narrow part of the grand canyon during a world record setting long distance motorcycle jump 69.5m. He left the jump ramp at 10 degrees angle above...

One end of a cord is fixed and a small 0.250-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.50 m as shown in the figure below. When θ = 16...

A 350-N child is in a swing that is attached to a pair of ropes 2 m long. Derive an algebraic expression for the the gravitational potential energy of the child–Earth system as a function of the...

phyisics: you are driving a vehical ( which can deccelarate at a rate of 9.5m/s^2) at a speed of 100 km/hr when you see a parked car 42m ahead. Assuming that you can stop the...

when a 200W, 400W, and 1000W bulbs are connected in series across a main of the three, the bulb which glows brightest is the 200W and not 1000W. What is the reason ?

A Coast Guard cutter detects an unidentified ship at a distance of 16.8 km in the direction 14.2° east of north. The ship is traveling at 22.5 km/h on a course at 38.9° east of north. The Coast Guard...
