In shot putting, many athletes elect to launch the shot at an angle that is smaller than the theoretical one (about 42°) at which the distance of a projected ball at the same speed and height is greatest. One reason has to do with the speed the athlete can give the shot during the acceleration phase of the throw. Assume that a 7.260 kg shot is accelerated along a straight path of length 1.650 m by a constant applied force of magnitude 380.0 N, starting with an initial speed of 2.500 m/s (due to the athlete’s preliminary motion). What is the shot’s speed at the end of the acceleration phase if the angle between the path and the horizontal is (a) 30.00° and (b) 42.00°? ( Hint: Treat the motion as though it were along a ramp at the given angle.) (c) By what percent is the launch speed decreased if the athlete increases the angle from 30.00° to 42.00°?

After the countdown at the beginning of a Mario Kart race, Bowser slams on the gas, taking off from rest. Bowser get up to a full speed of 25.5 m/s due to an acceleration of 10.4 m/s2. A)How much time does it take to reach full speed? B) How far does Bowser travel while accelerating?
The drawing in the image attached shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Side 1 has an area of 1.90 m^2, Side 2 has an area of 3.90 m^2, the electric field in magnitude is around 215 N/C. Please find the electric flux magnitude through side 1 and 2 combined if the angle (theta) made between the electric field with side 2 is 30.0 degrees. I believe side 1 is 60 degrees but could be wrong. Thank you.
