Mass m=25kg is released from rest from the top of a rough ramp, with coefficient of kinetic friction 0.50 between the block and the incline, of height h 2.5 m and length d=4.0 m. At the bottom of the ramp, the mass slides on a horizontal, frictionless surface until it compresses a spring of spring constant k = 12 N/m. m h d HMMMMM a. What is the speed of the mass at the bottom of the ramp? b. How far does the spring compress? c. How much work does gravity do on the mass when it slides down the ramp? d. How much work does the spring do on the mass during the compression? e. What is the total work done on the mass during the interval from the moment it is released to the moment the spring is fully compressed? Once compressed, the spring then pushes back on the mass. How high up f. the ramp is it rebounded?

A 1.30 kg block slides on a frictionless horizontal surface until it encounters a spring with a force constant of 520 N/m. The block comes to rest after compressing the spring by the distance of 2.50 cm.What was the initial speed of the block ? O 0.25 m/s 5.0 m/s O 31.6 m/s O 0.50 m/s

A 500-g block is released from rest and slides down a frictionless track that begins 1.86 m above the horizontal, as shown in the figure below. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 16.0 N/m. Find the maximum distance the spring is compressed. 50 0g h k

Nadia's parents have just bought her a trampoline. She can already reach a height of 1.2 m. If Nadia's mass is 50 kg, determine: a. With the conservation of energy, the speed at which it is thrown through the air to reach the height of 1.2m. b. The elasticity constant of the trampoline if it compresses like a spring, over 0.4 m after Nadia has jumped on it.

A box with m = 2 kg is launched up the circular ramp by compressing and releasing a spring with k=5kN/m. If the ramp has ρ=1.5m and the spring is compressed 0.1156 m, will the box be able to reach point B if the coefficient of kinetic friction of the ramp, μk = 0.3?

A 0.30-kg object is suspended from the ceiling at the end of a string of length 1.6 m. When pulled to the side and released, it has a speed of 2.7 m/s at the lowest point of its path. What maximum angle does the string make with the vertical as the object swings up?

A 10.0 kg block is released from point A in the figure. The track is frictionless except for the portion BC, of length 14 m. 10.0 kg 3.00 m B C k mmmmmm plz help and use g = 9.8 The block travels down the track, hits a spring of force constant k = 1,631 N/m, and compresses it 0.1 m from its equilibrium position as it comes to rest momentarily. Determine the coefficient of kinetic friction between surface BC and the block. Express your answer to at least two digits after the decimal point.

An athlete stretches a spring an extra 20.5 cm beyond its initial length. How much energy has he transferred to the spring, if the spring constant is 29.6 N/cm? 622 J 62.2 kJ 62.2 J O 622 kJ

A block of mass m 2.00 kg slides along a horizontal table with speed vo 9.50 m/s. At x = 0 it hits a spring with spring constant k95.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by u 0.100. How far has the spring compressed by the time the block first momentarily comes to rest? wwwww.wl Number 9.50 m/s m Ar ?
