A 0.500 kg sphere moving with a velocity given by (2.00î – 2.60ĵ + 1.00k) m/s strikes another sphere of mass 1.50 kg moving with an initial velocity of (−1.00î + 2.00ĵ – 3.20k) m/s. (a) The velocity of the 0.500 kg sphere after the collision is (-0.90î + 3.00ĵ − 8.00k) m/s. Find the final velocity of the 1.50 kg sphere. R = m/s Identify the kind of collision (elastic, inelastic, or perfectly inelastic). ○ elastic O inelastic O perfectly inelastic (b) Now assume the velocity of the 0.500 kg sphere after the collision is (-0.250 + 0.850ĵ - 2.15k) m/s. Find the final velocity of the 1.50 kg sphere. ✓ = m/s Identify the kind of collision. O elastic O inelastic O perfectly inelastic (c) Take the velocity of the 0.500 kg sphere after the collision as (−1.00ỉ + 3.40] + ak) m/s. Find the value of a and the velocity of the 1.50 kg sphere after an elastic collision. (Two values of a are possible, a positive value and a negative value. Report each with their corresponding final velocities.) a…

A cannon is rigidly attached to a carriage, which can move along horizontal rails, but is connected to a post by a large spring, initially unstretched and with force constant k = 1.31 x 104 N/m, as in the figure below. The cannon fires a 200-kg projectile at a velocity of 136 m/s directed 45.0° above the horizontal. 45.0° (a) If the mass of the cannon and its carriage is 5000 kg, find the recoil speed of the cannon. m/s (b) Determine the maximum extension of the spring. m (c) Find the maximum force the spring exerts on the carriage. (Enter the magnitude of the force.) N

launch angle. Passage Problems Alice (A), Bob (B), and Carrie (C) all start from their dorm and head for the library for an evening study session. Alice takes a straight path,

below the horizontal, and land 55 m horizontally from the end of the jump. Your job is to specify the slope of the ground so skiers' trajectories make an angle of only 3.0° with the ground on land- ing, ensuring their safety. What slope do you specify? T 9.5° -55 m

A convex mirror (f.=-6.20cm) and a concave minor (f2=8.10 cm) distance of 15.5cm are facing each other and are separated by a An object is placed between the mirrors and is 7.8cm from each mirror. Consider the light from the object that reflects first from the convex mirror and then from the concave mirror. What is the distance of the image (dia) produced by the concave mirror? cm.
