Two ice skaters, with masses of 50.0 kg and 65.0 kg , are at the center of a 30.0 m -diameter circular rink. The skaters push off against each other and glide to opposite edges of the rink. If the heavier skater reaches the edge in 10.0 s , how long does the lighter skater take to reach the edge?

A spring of negligible mass is compressed between two masses on a frictionless table with sloping ramps at each end. (Note: the masses are not attached to the spring in any way, and so will fly apart after release.) The masses are released simultaneously. The mass M1 is greater than that of M2. Select the appropriate symbol for each statement: G (Greater than), L (Less than), or E (Equal to). (If the first two are 'greater than,' and the last...

A 2.90-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring. (a) Determine the force constant of the spring, if the box compresses the spring 5.30 cm before coming to rest. (b) Determine the initial speed the box would need in order to compress the spring by 1.50 cm.

Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them as shown in the figure below. A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of v with arrow3m = 1.70 m/s. (a) What is the velocity of the block...

A mass m = 17 kg rests on a frictionless table and accelerated by a spring with spring constant k = 4916 N/m. The floor is frictionless except for a rough patch. For this rough path, the coefficient of friction is μk = 0.47. The mass leaves the spring at a speed v = 3.2 m/s. 1) How much work is done by the spring as it accelerates the mass? 2) How far was the spring stretched from its unstreched...

Where will they collide? (Explain your reason) (b) (6 Pts.) If they collide elastically head on, how high would 2m rise from the bottom of the bowl after the collision? (c) (10 Pts.)
