A 5000kg truck collides with an 800kg car. During the cllision, the truck applies 85,000N of force on the car. How much force does the car apply on the truck?

A 0.51 kg football is thrown with a velocityof 18 m/s to the right. A stationary receivercatches the ball and brings it to rest in 0.020s.What is the force exerted on the receiver?Answer in units of N.

A 3.0-kg block (A) is attached to a 1.0-kg block (B) by a massless spring that is compressed and locked in place, as Lee shown in the figure. The blocks slide without friction along A A the x-direction at an initial constant speed of v = O00 B 2.0 m/s. At lo В time to = 0 s, the positions of blocks A and B are XAi = 1.0 m and xB.i = 1.4 m, respectively, at which point a A,i A,f mechanism releases the spring, and the blocks begin to oscillate as they slide. If 2.0 s later block B is located at xB.f 7.3 m, what will be the position xA,f of block A? XA.f =

A 3.196E+3-kg Chevy Suburban on route 422 is stopped at the light in Annville heading eastbound. After the light turns green, the driver puts the pedal to the floor. The engine provides a monstrous 1.647E+4 N of forward force on the Suburban. The vehicle passes by the Allen Theatre at 11.3 m/s. Air resistance and friction contribute a 2.544E+3 N force that opposes the motion. Find out how far (in m) the suburban travels in the 3.80 s after it passes the Allen Theatre.
