A police car is traveling south towards the intersection that a robber’s car has just crossed traveling east. The robber’s car is currently traveling 55 mph. The police car’s speed is currently 63 mph. How is the distance between the cars changing when the cop is 1.2 miles from the intersection, and the robber is.5 miles from it? Be sure to answer in a complete sentence.
Please answer 15-17 with solution or explanation
As a technical engineer in the army, you are part of a team in charge of testing and commissioning a new tank
recently purchased by the artillery.
Field testing has revealed the following information:
1) The tank moves from rest to a speed of 70 km/hr in 10 seconds.
2) Using the breaking system, the tank is brought to a complete stop from a speed of 70 km/hr in 5 seconds.
You are required to address all the questions below providing all calculations, graphs, and explanations as
appropriate to back your answers.
First: Motion of the tank:
a) Find the average driving acceleration of the tank.
b) Calculate the average breaking acceleration of the tank.
c) For parts (a) and b above parts report your answers in US Customary Units (mile/hr) so that the information
could be shared with experts from the US.

- You are sitting in your car at a red light when you see a zombie standing still 65m in front of your car. You both begin to accelerate towards each other. Your car accelerates at 1.8 m/s^2 and the zombie accelerates at 0.6 m/s^2. How long does it take for you to strike the zombie? Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Please use grade 12 kinematics and label the variables as v1, v2, a (Acceleration), t (time), d (displacement) Thanks!arrow_forwardAfter a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by v=1.2i9.8tj where v is in meters per second and t is in seconds. The balls displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(x)dx You can think of the units and unit vectors as constants, represented by A and B.

- I did not understand this subject very well. (Average velocity, instantaneous velocity, average acceleration, instantaneous acceleration) And I am trying to understand with this question. Especially I can't get the "instantaneous" formulas in my head and I can't figure out why we did it. I would be happy if you could solve it in an explanatory way. Thanks.arrow_forwardA car starting from rest picks up at a uniform rate and passes three electric posts in succession. The posts are 360 m apart along a street road. The car takes 10 s to travel from the first post to the second post and 6 seconds to go from the second post to the third post. a. Set up the equations of motion that is required to solve the problem. b. Where did the car started from the first post?arrow_forwardWhat is the acceleration (in units of feet per second squared) of a car that goes from 16 mph to 75 mph in a 10.0 second time period?
