A 1500kg truck slows down from a speed of 25m/s to a complete stop over 3.0s. What is the average force that the brake pads must exert on the truck to complete this motion?
Homework Answers
Deceleration =25/3=8.33 m/s²
Mass=1500 kg
Average force by brake pads=8.33*1500=12500 N=12.5 kN

A 1500kg space ship (including fuel) is travelling through space at 25m/s[away from Earth) To gain a little more speed, the rocket expels 400kg of fuel out the back of the ship at 40.5m/s[toward the Earth] The speed of the ejected fuel is measured relative to the space ship. 17. By the time all of the 400kg of fuel has been ejected, what will be the new speed of the spaceship?

A truck of mass m slows from speed v0 to speed v in a time t. a) draw a force diagram for the truck. b) write an equation for the applied braking force. c) calculate the braking force if the mass of the truck is 3.0 x 10^3 kg and it is slowed from 32 m/s to 12 m/s in 6.0 seconds.

A driver traveling at 22 m/s slows down her 1500 kg car in order to not hit a brick wall. The distance between where she starts to brake and the wall is 75 meters. What is the average stopping force the driver experiences if she stops 5 meters before hitting the wall? (hint:the car takes 70 meters to stop, not 75) If the brake line bursts the driver decides to turn the in a wide arc parallel to the wall...

A 10,000-kg truck coasts to a stop from a speed of 40m/sec. The truck's motion obeys the equation V= ve^(-(k/m)t) with k=200kg/sec. a. about how far will the truck coast before reaching a complete stop?(round to the nearest whole meter) b. about how long will it take the truck's speed to drop to 7m/sec? (round to the nearest 0.1 sec.)
