A small block of mass m slides along the frictionless loop the loop track shown below. If it starts from rest at point A, what is the speed of the block at point B? (v = squareroot (10 g R)) What is the net force acting on the block at point C? (Don't forget the gravitational force.

In the figure, a 3.6 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo = 5.9 m/s, the height difference is h = 1.1 m, and Uk = 0.625. Find d. u=0

A block of ice slides along a frictionless horizontal track with a speed of 1.2 m/s. At the end of the track is a horizontally mounted spring. The ice block slides along the track until it makes contact with the spring causing it to compress. What is the speed of the ice block when the spring has been compressed by 60% of the maximum compression length?

1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...

Constants Find the kinetic energy K of the car at the top of the loop. Express your answer numerically, in joules. (Figure 1) A roller-coaster car may be represented by a block of mass 50.0 kg. The car is released from rest at a height h = 48.0 m above the ground and slides along a frictionless track. The car encounters a loop of radius R = 16.0 m at ground level, as shown. As you will learn in the...

I need help with the last three questions
the Loop A mass m -82 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R 7.8 m and finally a flat straight section at the same height as the center of the loop (17.8 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...

A kg block slides on a frictionless curved track The spring mounted at the right end of the track has a spring constant of 1250 N/m What speed must the block have at point A so that its speed at point B is 2 m/s? When the block runs into the spring, how much will the spring be compressed as it brings the block to a stop? A 10 kg block slides on a frictionless...

7. A block is released from rest at point P and slides along the frictionless track shown. At point Q, its speed is: I B) 2g(h- h) C) (h. - n12g D) E) (h, -h)/29 8. A ball of mass m, at one end of a string of length L, rotates in a vertical circle just fast enough to prevent the string from going slack at the top of the circle. Assuming mechanical energy is conserved, the speed of the...
