1. a. A truck of mass 2000 kg is moving with a velocity of 20 m/s....
A truck (with a mass of 3550 kg) is moving at 15 m/s. There is an accident up ahead so the truck driver applies the brakes and brings the truck to a stop. The law of conservation of momentum says that momentum cannot be created or destroyed. What happened to the momentum of the truck ?
A wagon is moving with a velocity of -2.0 m/s while having a 20 kg mass on top of it. There is a force applied to the wagon over a distance of 1.25 m. It then comes to a stop with a velocity of 0m/s. Please answer the questions. Show all work. 1. What is the total work done on the wagon? 2. What was the average force applied to the box to bring it to a halt?
The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...
A car of mass 2.0 x 103 kg is initially moving at 75 km/h when the brakes are applied and the car is brought to a stop in 25 m. Assuming the force that stops the car is constant, find the magnitude of that force that stop the car. A. - 15.73x103 N B. -17.3x103 N C. 16.73x103 N D. 12.73x103 N
car of mass 2000 kg and speed 20 m/s moving towards a junction from the south and collides with a bigger vehicle that moves at 20 m/s moving east. The two vehicles stick together and move q=10 degrees north of east. What was the mass of the vehicle moving north? How much energy was released as waste? t t y TQ Truck བད -X Px After | Car Before
QUESTION 12 A 1200 kg truck is moving in the -x direction at 26 m/s when it slams on its brakes. The truck comes to a stop in 0.83 s, moving a distance of 7.8 m in the process. What is the average force imparted by the brakes over this period, ignoring all other sorts of friction? 11800 N in the -x direction 11800 N in the +x direction 37600 N in the +x direction 37600 N in the -x...
) A 2000 kg truck is going 20 m/s collides with a brick wall bringing it to a stop. The truck is totaled, but the wall is fairly undamaged. If the collision lasts 100ms, find the average force exerted on the truck by the brick wall. How does this compare to the force that the truck exerts on the wall?
HELP ASAP 1500kg car moving at 16 m/s suddenly collides with a stationary car of mass 1000 kg Problem3 1500-kg car moving at 16.00 m/s suddenly collides with a stationary car of mass 1000 kg a) What is the total initial momentum? b) If the two vehicles lock together, what is their combined velocity immediately after the collision? c)What is change in momentum? d)What is the impulse? e) What is the average force acting on the stationary car by the...
1. A 10,000 KG truck is traveling at +20 m/s. What would happen to the momentum of the truck if it increases in velocity in the same direction? 2. A 120 KG rugby player is running toward another player at 5 m/s. How much force needs to be applied over one second in order to bring him to a stop? 3. if the acceleration of an object decreases, what happens to the inertia? A 10,000kg truck is traveling at +20m/s....
A truck with a mass of 1510 kg and moving with a speed of 14.5 m/s rear-ends a 671 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. m/s vcar truck m/s
