A glider of mass 0.75 kg moves right on a frictionless air tract at 4 m/s and collides head-on with a second glider of mass 0.15 kg moving left at 6m/s. Find the final velocities of the two gliders if the collision is perfectly elastic.

A 6.75-kg bowling ball moving at 8.95 m/s collides with a 0.875-kg bowling pin, which is scattered at an angle of θ = 24.5° from the initial direction of the bowling ball, with a speed of 11.2 m/s. Calculate the magnitude of the final velocity, in meters per second, of the bowling ball.

he figure shows an approximate plot of force magnitude F versus time t during the collision of a 56 g Superball with a wall. The initial elocity of the ball is 35 m/s perpendicular to the wall, in the negative direction of an x axis. It rebounds directly back with pproximately the same speed, also perpendicular to the wall. What is Fmax, the maximum magnitude of the force on the ball from the all during the collision? Number i .98 Units N F 9 t(ms) b

A  12.70 g bullet has a muzzle velocity  (at the moment it leaves the end of a firearm)  of  430 m/s when fired by a rifle with a weight of 25.0 N. Calculate the recoil speed (in m/s) of the rifle.

A cue ball traveling at 6.57 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision.   (b) Find the speed of each ball after the collision.

A 0.150-kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.80 m/s. It has a head-on col- lision with a 0.300-kg glider that is moving to the left with a speed of 2.20 m/s. Find the final velocity (magnitude and direction) of each glider if the collision is elastic.

A) 5.10 kg squid initially at rest ejects 0.250 kg of fluid with a velocity of 10.8 m/s. What is the recoil velocity (in m/s) of the squid if the ejection is done in 0.100 s and there is a 5.05 N frictional force opposing the squid's movement? (Enter the magnitude.) B)How much energy (in J) is lost to work done against friction?

In Figure, mass m1= 2 kg with a velocity v1i =10 m/s moving in x direction makes elastic collision with m2= 4 kg that is initially at rest.(a) Find the velocity of m1 after the collision.(b) Find the velocity of m2 after the collision.(c) Find the maximum height h to which m2 rises after the collision

A tennis ball of mass 57.0 g is held just above a basketball of mass 607 g. With their centers v as shown in the figure below. | (a) Find the magnitude of the downward velocity with which the basketbal reaches the ground. m/s (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is stis moving down. Next, the two balls meet in an elastic collision. To what height does the tennis ball rebound) Need Help? Road ers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.25 m, Master

Two freight trains have a complete inelastic collision at a track crossing. Engine 1 has a mass of 1.4 x 10^4 kg and is  initially travelling at 45 km/h [N]. Engine 2 has a mass of 1.5 x 10^4 kg and is initially travelling at 53 km/h [W]. Calculate  the final velocity.
