Four forces are acting on a 6 kg box The Normal Force, the Weight, an applied force, and a friction force of 2.5 N that counteracts the applied force. The box is accelerating at a rate of 4 m/s ^ 2 Draw the box, label, and calculate the forces

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
