...west.? In a head on collison, a 4000kg truck going east strikes a 1000kg car going 20 m/s west. What is speed and direction? And how much kinetic energy is lost?

...head on with a light post. If th....? 1.A 2.15 x 103 kg truck travels at 30.0 m/s when it collides head on with a light post. If the truck comes to a complete stop in 0.45 s, what is the average force exerted on the truck by the post during the collision? please show me how to do this question

exactly quadruple the car’....? 15.A car moves east at 10.0 m/s when it collides with a stationary truck with exactly quadruple the car’s mass. If the two vehicles lock together, what is the velocity of their combined mass immediately after the collision? please show me how to do this question

It's an automatic but under "D" there is something that says m/s. What does that mean?

What is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 57.0 m?

...turn red. After 0.600 s has elapse? Suppose a car is traveling at 15.0 m/s, and the driver sees a traffic light turn red. After 0.600 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 9.00 m/s2. What is the stopping distance of the car, as measured...

its engine cuts out. For the next ten? A car is traveling along a straight road at a velocity of +34.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is 1. For the next five seconds, the car slows down further, and its average...

botttom.? what is distance traveled before rest

(a) Find the car's centripetal acceleration? (b) What minimum coefficient of static friction between the tires and road is necessary for the car to round the curve without slipping?

i keep getting 6.09x10^8.... but it keeps telling me that i am wrong

What is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 41.5 m?

Determine? A satellite moves in a circular orbit around the Earth at a speed of 5034 m/s. Determine (a) the satellite's altitude above the surface of the Earth and (b) the period of the satellite's orbit.

if a bike accelerates from 5 m/s to 10 m/s in 5 seconds, how far has it traveled? which equation do i use and how do i use it?

together and move forward.? (a)What kind of collision is this? Answer ______________________________________ (b)What is the momentum of the truck before it strikes the car? Answer ____________________________________ (c)What is the speed of the car and truck as they move forward (connected...

A bike accelerates from 0.0 m/s to 3.6 m/s in 4 s. What distance does it travel?

(a) If it accelerates at the rate of 0.5 m/s2 for 8.0 s, what is the final velocity? (b) If, instead of accelerating as in part (a), it accelerates at the rate of -0.6 m/s2, how long will it take to reach a complete stop.

(a) Find the time of one revolution. (b) Find the radial acceleration of the satellite in its orbit.

momentum is 56,250 kg.m/s using the formula M=m(v). the formula you listed is for like impulse or something which wouldnt apply to this problem
