An object of mass 3.00 kg, moving with an initial velocity of 4.97 i m/s, collides with and sticks to an object of mass 2.87 kg with an initial velocity of -3.78 j m/s. Find the final velocity of the composite object. V = m/s î + m/s j

A professional golfer swings a golf club, striking a golf ball that has a mass of 55.0 g. The club is in contact with the ball for only 0.00310 s. After the collision, the ball leaves the club at a speed of 32.0 m/s. What is the magnitude of the average force (in N) exerted on the ball by the club?

= A small block of mass m. = 0.540 kg is released from rest at the top of a frictionless, curve-shaped wedge of mass m₂ 3.00 kg, which sits on a frictionless, horizontal surface as shown in Figure a. When the block leaves the wedge, its velocity is measured to be v₁ = 3.00 m/s to the right as shown in Figure b. m1 mi m2 ml? b (a) What is the velocity of the wedge after the block reaches the horizontal surface? m/s to the left (b) What is the height h of the wedge? m

A 3.29 kg object initially moving in the positive x-direction with a velocity of +4.50 m/s collides with and sticks to a 1.77 kg object initially moving in the negative y-direction with a velocity of -2.61 m/s. Find the final components of velocity of the composite object. (Indicate the direction with the sign of your answer.) Vfx = m/s Vfy = m/s
