A very small Steel marble is shown rolling at a constant on a horizontal table
A very small Steel marble is shown rolling at a constant on a horizontal table. The marble leaves the table at M, falls, and hits the ground at P. This is illustrated in the diagram below which is drawn to scale. Calculate the time it took the marble to travel from L to P.

Suppose that while a mining cart is rolling along a straight, frictionless, horizontal track with some initial speed, it starts to rain. If the rain falls vertically into the cart and begins to accumulate within it, flooding the cart, determine the following 19. is the momentum of the system conserved in the horizontal direction? a. Yes b. No 20. Is the momentum of the system conserved in the vertical direction? a. Yes b. No 22.If a 1200 kg train car...

ner 16/10/2018 Please answer all questions below. 1. Consider a cart rolling on the track shown below. The cart starts from an initial height of ho, and rolls around a circular loop of radius R. The cart is of mass m and the friction between the cart and the track 1s negligible. (a) ( Points) What is the largest radius of the loop, Rmaz, that the cart can complete without losing centact with the track? (b) (3 Points) At which...

A positive charge q1 = 2.70 μC on a frictionless horizontal surface is attached to a spring of force constant k as in the figure below. When a charge of q2 = -8.60 μC is placed 9.50 cm away from the positive charge, the spring stretches by 5.00 mm, reducing the distance between charges to d = 9.00 cm. a)Write, in symbols, the equation of the force that the charge q2exerts on the charge q1.b)Write, in symbols, the equation of...

Consider a frictionless track as shown in the figure below. A
block of mass m1 = 5.60 kg is released from circled A. It makes a
head-on elastic collision at circled B with a block of mass m2 =
19.5 kg that is initially at rest. Calculate the maximum height to
which m1 rises after the collision.
