A Force of F = 90 N Is Exerted on Mass

Question 105

Multiple Choice

A force of F = 90 N is exerted on mass m1 as shown. Both m1 and m2 accelerate to the right at 3 m/s2 along the frictionless surface. The force F makes an angle of 25 degrees to the horizontal. Calculate the force that the horizontal surface exerts on mass m1. (m2 = 10 kg)  A force of F = 90 N is exerted on mass m<sub>1</sub> as shown.
