2. You ask a tall person to help you pull the cart. The second person applies a force of 100 Newton up 45 degrees form the horizontal. Determine the net force of both forces horizontally and vertically. Show a free-body diagram of the cart. 3. What is the acceleration of the cart when only you are pulling it.? 4. What is the acceleration of the cart when both of you are pulling the cart? 5. A circus performer wants to be shot out from cannon. He wants the range to be 50 meters. For crowd excitement he wants the angle of the cannon to be 60 degrees from horizontal. He will land on a net that is the same height as the end of the cannon. Determine the initial velocity needed for this stunt. 6. An object is launched at a 45 degree angle from the top of a hill. The initial speed is 30 m/s. Where in the valley below will the object land? What will be the velocity (magnitude and direction) just before the object hits the ground? Show the ball in a free- body diagram. 7. What is the weight of the following 3 boxes when stacked on top of each other? Box 1 is 100 kg, box 2 is 50 kg, and box 3 is 25 kg. 8. You walk 2 km east, then 3 km north, then 5 km west. What is your displacement. a. Use the graphical method to determine the displacement. b. Use components to determine the displacement.

Explanation / Answer

3. in this question data is missing about what is the force apply by me

4) force by another one is 100 N

it will add in my force with direction

Horizintal forceFx = F cos(45) =100*cos(45)=100*0.707 = 70.7Newton in X positive direction

and Acceleration in X direction is Ax=Fx /M(mass of cart)

and Verticle force =F sin(45) downward =70.7 Newton in Negative direction of Y

and Acceleration in Y direction is Ay=Fy/M(mass of cart)
