In a steel works the scrap metal is transported to the furnace in loaded wagons of mass 820 kg. One such wagon accelerates from a stationary position to a velocity of 10 m/s in a time of 12 seconds whilst ascending 30° to the horizontal. The frictional resistance to motion is 500N. Use Kinetic techniques to determine: a) The tractive effort (force) required to accelerate the wagon up the incline. b) The work done in ascending the slope.
A particle moves along the x axis. Its position as a function of time is given by x = 6.8t + 4.5t2, where t is in seconds and x is in meters.

Problem 5: In section 8.5, we learned how to use matrix multiplication to encode and decode message. To begin a cryptogram, which is a message written according to a secret code, we assign a number to each letter in the alphabet as listed below: 0= (blank space) 5=E 10=J 15=O 20=T 25=Y 1=A 6=F 11=K 16=P 21=U 26=Z 2=B 7=G 12=L 17=Q 22=V 3=C 8=H 13=M 18=R 23=W 4=D 9=I 14=N 19=S 24=X (1) (5 points) Write the uncoded 1 \times 3 row matrices for the message: SPRING IS HERE (2) (5 points) write a cryptogram for (encode) the message using the given encoding matrix $\begin{bmatrix} 1 & 2 & 2 \\ 3 & 7 & 9 \\ -1 & -4 & -7 \end{bmatrix}$
