A 0.20-kg block slides from rest down a frictionless track from a height of 1.5 m, and encounters a loop that is 1.0 m high. (a) What is the speed of the block at the top of the loop? (b) The block is slowed by a spring at the bottom of the track. If the stiffness of the spring is 0.90 kN/m, how far does the block slide before coming to rest?

Answer #1

I have taken value of g as 9.8m/s^2 . If one takes the value of g as 10m/s^2, answer will vary a bit.

A 500-g block is released from rest and slides down a frictionless track that begins 2.26 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 29.5 N/m. Find the maximum distance the spring is compressed. m A 500-g block rests at the top of a track on a horizontal platform. From this platform, the...

A block of mass 13.0 kg slides from rest down a frictionless 39.0° incline and is stopped by a strong spring with k = 2.70 ✕ 104 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed? m

A 2.00 kg block is released at the top of a frictionless track from a height of 1.50 m. The block travels down the track to a horizontal region where it then attaches to a massless spring with spring constant 400 N/m. What will be the amplitude of the resulting block-spring system?

A mass m = 86 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 19.7 m and finally a flat straight section at the same height as the center of the loop (19.7 m off the ground). Since the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it must be released above the top of the...

A 2.0 kg block slides on a frictionless horizontal surface with an initial speed of 15.0 meters per second. The block then encounters a 35.0o incline, where the coefficients of static and kinetic friction are 0.20 and 0.10 respectively. Determine how far up the incline the block will slide, and if the block will slide back down or remain stationary on the incline (use a force analysis to determine this)

1.A small block of mass 3.5 kg starting from rest slides down on an incline plane of height 2.0 m, 40 degrees with respect to horizontal (Fig. 2). The coefficient of kinetic friction between the block and the incline plane is 0.25. At the end of the incline plane, the block hits the top of a hemispherical mound of ice (radius 1.0 m) , loses 75% of final kinetic energy (KE=0.5mv*v) before the collision, then slide down on the surface...
