A rocket sled is propelled by a solid propellant rocket motor of 6.027×10^5 N thrust. If the sled travels 1.776×10^3 m while attaining a top speed of 8.240×10^2 m/s.

i found the acceleration = 1.912×10^2 m/s^2
but what is the mass of the rocket sled?????

f-K*x-D*(dx/dt) = M*(d^2x/dt^2)

where:

f = an external force, positive in the +x direction (an initial "impulse" of +100,000N for .0004 seconds)
x = displacement of mass M, in meters (initially stationary at x = 0)
K = a spring constant (15 N per meter)
D = a damping coefficient (40 N-second per meter)
M = a mass (80 kg)

Plot x as a function of time, showing how it varies as a result of the "impulse" Label the axes with appropriate dimensions and plot enough points to reveal the general behavior of x.
