What is the magnitude F of the force
Setting the angle θ = 0; the m1 mass = 1 kg; the m2 mass = 3 kg, μ = 0.7, calculate theoretically the value of the force of friction, the tension, and the acceleration.
A small 1600 kg rocket applies its thrusters from rest to generate a net force of F=1600t+2990 newtons, where tt is time. Assuming no air resistance, calculate the rocket's velocity, v, in m/s after 8 seconds.
Enter your answer for v in m/s, correct to three significant figures: ....... m/s
