Anna Litical is riding on The Shock Wave at Great America. Anna experiences a downward acceleration of 12.5 m/s2 at the top of the loop and an upward acceleration of 24.0 m/s2 at the bottom of the loop. Use Newton's second law to determine the normal force acting upon Anna's 50-kg body at the top and at the bottom of the loop.

Two forces act on a 21-kg object. One force has magnitude 65 N directed 59° clockwise from the positive x-axis, and the other has a magnitude 35 N at 32° clockwise from the positive y-axis. What is the magnitude of this object's acceleration? 2.8 m/s? 4.4 m/s? 3.8 m/s2 3.2 m/s? O O

Be sure to review Examples 5.13, 5.14, and 5.15 (Section5.3) before attempting these problems. Figure You pull on a crate using a rope as in (Figure 1), except the rope is at an angle of 20.0° above the horizontal. The weight of the crate is 325 N, and the coefficient of kinetic friction between the crate and the floor is 0.270. What must be the tension in the rope to make the crate move at a constant velocity? Express your answer with the appropriate units. T₁ = Submit Part B 0 4 Value n1 = ША Request Answer Units Value What is the normal force that the floor exerts on the crate? Express your answer with the appropriate units. @ Units ? ?

Answer the question correctly. Thank you!
