- 3M- Please I want a solution of all sub-part questions in detail by typing them. Thanksarrow_forwardA 50.0-g Super Ball traveling at 30.0 m/s bounces off a brick wall and rebounds at 17.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.50 ms, what is the magnitude of the average acceleration of the ball during this time interval?? m/s2arrow_forwardA Ferrari traveling well over the posted speed limit, passes a parked Tennessee State Trooper who decided to give chase. It takes the trooper 4.6 seconds to turn on the 'blue lights' and get the 'at rest' PW5000 powered Dodge interceptor moving. Then 8.3 seconds more to accelerate to its top speed and 63 seconds more to catch up with the speeder 3.5 km down the highway from the trooper's parking spot. Determine the average speed of the Ferrari over this distance in km/hrarrow_forward
- A horse canters away from its trainer in a straight line, moving 44 mm away in 8.5 ss . It then turns abruptly and gallops halfway back in 2.0 ss . Part A Calculate its average speed for the entire trip. Express your answer using two significant figures. Part B Calculate its average velocity for the entire trip, using "away from the trainer" as the positive direction. Express your answer using two significant figures.arrow_forwardHi there, I need some help. Can anyone walk me through how to complete this problem? I have tried working this out 4 times and each time was wrong. I don't know what I'm doing incorrectly! Entrance and exit ramps for freeways are often circular stretches of road. As you go around one at a constant speed, you will experience a constant acceleration. Suppose you drive through an entrance ramp at a modest speed and your acceleration is 3.0 m/s^2. What will be the acceleration if you double your speed?arrow_forwardAs a technical engineer in the army, you are part of a team in charge of testing and commissioning a new tankrecently purchased by the artillery.Field testing has revealed the following information:1) The tank moves from rest to a speed of 50 ??/ℎ? in 100 seconds.2) Using the breaking system, the tank is brought to a complete stop from a speed of 50 ??/ℎ? in 5 seconds.3) The maximum speed achievable by the tank is 90 km/hr.You are required to address all the questions below providing all calculations, graphs, and explanations asappropriate to back your answers. Hint: make sure you are using consistent unitsFirst: 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 so that the information could beshared with experts from the US.d) How long would it take the tank to travel a distance of 12 km. Assume constant acceleration equal to…arrow_forward
- 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_forward4. Can you please THOROUGHLY explain how did you solve this? I need it in step by step format because I'm going to explain it in class. Please help me, thank youarrow_forwardAs 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 ??/ℎ? in 10 seconds. 2) Using the breaking system, the tank is brought to a complete stop from a speed of 70 ??/ℎ? in 5 seconds 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.arrow_forward
