A shot putter exerts a force of 100N acting forward and upward on a 40N shot put at an angle of 60° from horizontal. Other than gravity, the weight of the shot put (40N) is the only external force acting on it. a. What was the vertical component of this force? b. What is the horizontal component of this force? c. How big was the NET force (sum of all external forces) acting on the shot put? (remember gravity is...

The vertical ground reaction force acting under a runner’s foot is 1500 N, while the frictional force is 700 N acting forward. What is the resultant of these two forces? What is the angle of the resultant force with respect to horizontal?

The same person walking takes a longer stride. He still exerts a downward and forward force of 180 pounds but now at an angle of -45 degrees (315 degrees) to the ground. Resolve the forces into their perpendicular (vertical) and parallel (horizontal) components and label each component also calculate the magnitude of the component forces using trigonometric functions. Show ALL of your work use appropriate symbols.

Question 6 20 marks You should be able to answer this question after studying Unit 5 A mountain rescue team is preparing to move a stretcher (with an injured climber) down a flat slope. The combined mass of the climber and stretcher is 110 kg, and the slope makes an angle of 15° with the horizontal. The stretcher is held at rest by...

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

Surface Tension and Bubbles Surface tension is a force caused by the attraction of liquid molecules on a boundary surface for each other. It acts tangential to the surface and is modeled as a single number, the surface tension Consider a square film on a wire frame. The bottom edge is movable and, when the frame is vertical, as shown, the surface tension of the film pulls...

HW#5 Functions and Arrays
For HW#5 we will return to the state method of solving the
ballistic projectile problem with added twists. The goal will be to
hit a target 1000 meters east of your cannon but the wind is
blowing from the south. Your initial muzzle velocity is fixed at
110 meters per second, but you can control the elevation and
azimuth angles of your aim. Elevation angle is measured up or down.
Azimuth angle is measured right or...
