Gas guns are used to investigate the properties of materi- als subjected to high-velocity impacts. A projectile is accelerated through the barrel of the gun by gas at high pressure. Assume that the acceleration of the projectile in m/s² is given by a = c/s, where s is the position of the projectile in the barrel in meters and c is a constant that depends on the initial gas pressure behind the projectile. The projectile starts from rest at s = 1.5 m and acceler- ates until it reaches the end of the barrel at s = 3 m. Determine the value of the constant c necessary for the projectile to leave the barrel with a velocity of 200 m/s.
30 mg = 1600 kg ma = 1200 kg VA1 = 50 km/h V81 = ? The two cars, A, and B, collided at right angles at the intersection. During the collision, the cars became entangled (AB) and moved off together to bump into a huge old tree. Calculate the velocity (km/h) of car B just before the collision with car A at the intersection. Right after bumping with the tree, determine the new velocity of the "entangled" cars. Also, compute the percent energy lost from the cars after the two collisions occurred. Neglect the geometry of the cars before and after the collision. Coefficient of restitution between the entangled cars (AB) and the tree (C), e43c = 0.18

the vertical ground reaction force from a force plate during the contact phase for a 55 kg runner. If the initial vertical velocity of the runner when she first makes contact with the plate is directed 0.40 m/s downwards, determine the following:a) the vertical velocity (including direction andmagnitude) just as the runner comes off the plate at the end of ground contact. (Average net force includes the effect of gravity and thevertical ground reaction force acting on therunner) b) the average vertical ground reaction forceduring the ground contact phase of the run
