![]() ![]() Two objects moving with a speed v travel in opposite directions in a straight line.Determine the tension force between the truck and the trailer, and determine the force with which the truck is pulling. Both are accelerating at a rate of 0.45 m/s^2. A large truck with a mass of 3200 kg is pulling a trailer with a mass of 2400 kg.a car traveled 60 km in 2 hours, 84 km in the the amount of time needed to travel the distance** b. speed is the ratio of the distance an object moves toĪ. Imposed so in close, can be able to, um, six times 10 to the power off big three seconds times 2000 u 10 over to plus two times 10 to the power of 93 seconds, times next by 100 Newton and this would give us the imposed is about minute and 10 seconds, a necessity answer for this question.In a 1-dimensional problem, a single force acts on a 10 kg object and is given the equation F=ax+b where a=250 N/m, b=25 N, x is position of object. ![]() Can you go to six milliseconds? Which is because you six times 10 spanning three seconds and each one is 2010 all to commit go to to milliseconds, which is two times 10 spawning three seconds and edge two is equal to 9500 Newton. ![]() H two is the highest for smaller triangle. Otherwise the base fall for the larger triangle and which ones? The heights for a louder triangle And L two is the base for the smaller triangle. Okay, because those two small triangles have seven days and heights. OK, which would you mentioned? Have at one stage while we're two plus Elton with hands age too. An aerial photograph is actually equal to the area of the larger triangle minus two area of the small triangle. So the impose can be good to the integral off the force versus time function, which it can be also equally area of the grab. So if we divide by Delta T than we get F now in this case, Delta T is eight and that is the time taken for the car to stop, so 45,000 divided by eight is equal to 5000 600 25 Newtons. So we have just calculated f Delta T and now he wants calculate F. Now the next part of the question wants us to calculate the average force on the car and that is this f here. The change in momentum and then full impulse is simply the mass 1500 times by 30 and this is equal to 45,000 and that is in units of killer ground meters per second. So in this case, the change in velocity delta v his 30.Īnd that is because the car is going from 30 meters protect per 2nd 20 meters per second. ![]() After all, Titi is equal to the change in momentum and Delta V. So if we remember from our equations, we know that impulse. So we're told in the question that the car is 1500 kilograms, that it's initially going at 30 meters per second. In this question were wanting to find the impulse and average force acting on the car when it takes eight seconds to stop. Multiplication one day by 24 Howard which is equal to 181.71 days as our answer. So on simplification, I get the value as 4361 Harvard. So I just multiply by one by mhm one hour by 36 00 2nd. Do you have to edge? Dirty? Is equal to 66.75 85 page multiplication 10 to the 48 kg meter purse again, bye 4 to 4.6 Newton which is equal to 1.57 multiplication, 10 to the power seventh again. I am so just putting the value in this expression. Physical to 2.3 Multiplication.ġ2.6 KZ multiplication 2.61 multiplication 10 to the 48 m purse again, which is equal to 66 0.75 85 eight multiplication 10 to the 48 kg meted. So just putting the value I can write one by understood one minus 10.8 70 square on solving it further, I can idea express an l one by under rule point 2431 which is equal to 2.3 now the value of P can be calculated as just look at it carefully. The value of Kama is equal to one by under hood one minus B squared by C Square. ![]()
