ACTIVITY 3PROBLEM SOLVINGCIRCULAR MOTIONCircular motion is another example of two-dimensional motion. When we analyze objects in circular motion,three quantities are used to portray it, hence speed, acceleration, and force. These factors are responsible in affectingthe behavior of an object that is moving in circular path.Read, analyze, and solve the following problems using the GUFSA template. Show your complete solution.Round off your final answer to the nearest hundredths.1. A 750-kg car moving at 8 m/s takes a turn around a circle with a radius of 20.0 m. Determine:a. the acceleration of the carb. the net force acting upon the car SHIFTB. Vertically Launched Projectiles1. A ball is kicked at an angle of 35° with the ground.a. What should be the initial velocity of the ball so that it hits a target that is 30 m away at a height of 1.8 m?ww.a dd esob. What is the time for the ball to reach the target?

Suggest some likely sources of error that could be responsible for the difference between your measured and predicted values for the horizontal distance traveled by the projectile at the different angles used in this experiment. “Human error” is not acceptable without saying specifically what error the human could have made. “Calculation error” is also not acceptable—if you are worried about whether the calculation is correct, consult with your classmates and/or someone you trust to do the calculation correctly. PROCEDURE Part I Place a marble launcher on the table, oriented so it points straight upward (θ = 90°). Pull the launch mechanism back to the first (nearest) launch position and place a marble into the launcher. Practice quickly releasing the launch mechanism and get a sense for the maximum height the marble will reach after it is launched. Hold a meter stick beside the marble launcher so that the zero end is beside the marble. Launch the marble and record the maximum…
