As part of an obstacle course, an athlete must kick a soccer ball into al meter wide and 10 meter deep pit such that the ball hits a target at the bottom of the pit. In practice, a dynamics student that is participating in the race kicks the soccer ball such that the soccer ball will bounce off the far wall of the pit 5 meters below the surface and head towards the target. If the velocity of the ball before striking the wall at point at point A is vA=3.21- 10j , determine the t-component of the ball velocity vector (in m) after striking the wall. The size of the ball and the target are negligible relative to the dimensions of the pit, the gravity acceleration must be considered as g = 10 and the coefficient of restitution at point A is e =0.55. 5 m 10m Im 目

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
A constant force of ''F'' acts on a mass as shown. The mass starts its motion from rest at position 1, the unstretched length of the spring is 250 mm, and the spring modulus is k=1,5 k?/m. Neglecting the friction, determine the required force ''F'' to cause the 2−kg mass to have a speed of v2=1,5 m/s at position 2.
