Two vehicles, A and B, move through an intersection as seen in the image above. At this instant, vehicle A's speed is 40 km/h and vehicle B's speed is 10 km/h. What is the relative velocity of B with respect to A i.e. B/A? Write your answer in Cartesian vector component form using integer values. Enter negative values if necessary. "B/A = Number + Number j km/h

Velocity. Suppose the distance travelled by a tanker ship departing from port is given implicitly by the equation 2-4st-75³-0 Where s is the distance in kilometres and it is time in seconds (s). Use implicit differentiation to calculate the velocity of the ship when s= 40 and 14 seconds. Note: Enter your solution as a decimal rounded to four (4) decimal places without units.

Two tractors leave point o at the same time and drive in the directions shown. Tractor A is traveling at a TIL 8 m constant speed of ₁9 Tractor B is traveling at a constant speed of = 13 - Hint: 1. Use constant acceleration equations to find time. VA A Variable 0₁ 0₂ -16.787 = 16.806 0₁ values for the figure are given in the following table. Note the figure may not be to scale. value 30 degrees 35 degrees t= 29.751 a. Determine the velocity of tractor A relative to tractor 6, 4, express as a Cartesian vector. b. Determine the magnitude of the velocity of tractor A relative to tractor 8, c. How long after leaving point O will the tractors be 500 m apart? Round your final answers to 3 significant digits/figures. VA = ||= xi -0.809 X 8 0₂ m VB B TIL x= X

A particle begins moving from rest from the origin in one-dimensional motion. It has a constant acceleration of 9 m/s2 until it reaches a position of 20 m. What is the particle's speed at 20 m? Write your answer to three significant figures. The particle's speed at 20 m is Number m/s.
