CT (2.3) HMW:Additional Exercises. (2.4) Let ŕ(t) = (t,, t22). Evaluate the derivative of (t) Calculate the derivative of V(t) (t) whenever V(1) = (-1, 1, -3) and V'(1) = (1,-2,5). • HMW: Additional Exercises. Assume that a wagon is pulled horizontally by an exercising force of 5 lb on the handle at an angle of 45 with the horizontal. (a) Illustrate the problem using a rough sketch. (b) Determine the amount of work done in moving the wagon 30 lb. (2.5) HMW:Additional Exercises. Let the vector (3500, 4250) gives the number of units of two models of solar lamps fabricated by electronics company. Assume that the vector a= (1008.00, 699,99) gives the prices (in Rand-ZA) of the two models of solar lamps, respectively. (a) Calculate the dot product of the two vectors a and V. (b) Explain the meaning of the resulting answer you obtain in the question above. (e) Let assume that the price of original price of the solar lamps has decreased by 10%. Identify the vector operation used for this case. (2.6) HMW: The force exerted on a rope pulling a toy wagon is 30 N. The rope is 30 above the horizontal. (a) Illustrate the problem by means of a sketch. (b) Determine the force that pulls the wagon over the ground. CT (2.3) HMW:Additional Exercises. (2.4) Let ŕ(t) = (t,, t22).
