A 1.07 kg block is held in place against the spring by a 31 N horizontal external force. The external force is removed, and the block is projected with a velocity v1 = 1.2 m/s upon separation from the spring. The block descends a ramp and has a velocity v2 = 1.6 m/s at the bottom. The track is frictionless between points A and B. The block enters a rough section at B extending to E. The coefficient of kinetic friction is 0.34. The velocity of the block is v3 = 1.4 m/s at C. The block moves on to D, where it stops. (a) Find the height of the ramp. (b) Find the distance that the block travels between points B and C. (c) Find the coefficient of elasticity for the spring?
Thanks for asking.

(10 points) A block of mass m = 0.80 kg is held in place against a spring with spring constant k = 3000 N/m, compressing it a distance of 0.022 m. The block is released from rest and is projected to the right and down a ramp of height h = 1.5 m, as shown in the figure below. The entire surface is frictionless until point B, after which the coefficient of friction between the block and the surface is...
PHYS1030 Newtonian Mechanks QUESTION #10: A 22-kg block is held a rest against a spring of force constant k # 930 N/m as shown below. Initially the spring is compressed a distance of 15 em. When the block is released, it slides across a surface that is frictionless except for a rough patch of width 60.0 cm that has a coefficient of kinetic friction μ.-0.34. Find the block's speed (m/s): (a) before crossing the rough patch b)after crossing the rough...
A 2.1.0-kg block is accelerated from rest by a compressed spring (ks = 545 N/m). The block leaves the spring at the spring’s relaxed length. The block then travels along a rough horizontal with a coefficient of kinetic friction μk = 0.240 a distance of x = 6.90 m before frictional force stops the block. What was the original compression distance of the spring?
A 195 g block is pressed against a spring of force constant 1.60 kN/m until the block compresses the spring 10.0 cm. The spring rests at the bottom of a ramp inclined at 60.0° to the horizontal. Using energy considerations, determine how far up the incline in m) the block moves from its initial position before it stops under the following conditions. (a) if the ramp exerts no friction force on the block (b) if the coefficient of kinetic friction is 0.360...
3.0 - 6.00 m ASSO 13.0-kg block is released from point A with initial speed of -2.0 m/s ( block is given a push up or down the ramp). The track is frictionless except for the portion between points B and C which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. Determine the...
a block with mass 0.7 kg is forced against a horizontal spring, compressing the spring a distance of 0.2m. The spring constant k is 125 N/m. When released, the block moves on a horizontal tabletop for 0.5m and then up a ramp. The coefficient of kinetic friction between the tabletop and block is 0.3, but the ramp is frictionless. To what vertical height does the block go? show work please
A 195 g block is pressed against a spring of force constant 1.50 kN/m until the block compresses the spring 10.0 cm. The spring rests at the bottom of a ramp inclined at 60.0° to the horizontal. Using energy considerations, determine how far up the incline (in m) the block moves from its initial position before it stops under the following conditions. (a) if the ramp exerts no friction force on the block m (b) if the coefficient of kinetic...
why do we reverse the direction of one of the two motion d 14.0-kg block is released from point A with initial speed of -3.0 m/s ( block is given a push up or down the ramp). The track is frictionless except for the portion between points B and C which has a length of 6.00 m.
