Question

(5%) Problem 2: The mass of the system of the rocket sled shown in the figure is 2100 kg, and the force of friction opposing the motion is known to be 660 N. The thrust for the rocket sled is 2.59 × 104 N Randomized Variables f=660 N ©theexpertta.com What is its acceleration in m/s2?

Explanation / Answer

In horizontal,

Fnet = m a

Fnet = F_thrust - f = m a

(2.59 x 10^4) - 660 = 2100 a

a = 12 m/s^2 ......Ans
