A If The Rocket Sled Shown In The Figure Below Starts With Only One Rocket Burning What Is The Magnitude Of Its Accel 1 (112.37 KiB) Viewed 47 times
If the rocket sled shown in the figure below starts with onlyone rocket burning, what is the magnitude of its acceleration (inm/s2)? Assume that the mass of the systemis 2120 kg, thethrust T is 1.4 ✕ 104 N,and the force of friction opposing the motion is known tobe 765 N.
m/s2
(b)
Why is the acceleration not one fourth of what it is with allrockets burning? (The acceleration when all four rockets areburning is 26 m/s2. The force of frictionremains 765 N.)
