A ball of mass m moves along a track in the shape of vertical circular loop. There are 2
forces acting on the ball -- the normal force exerted by track (Ntrack) and gravity (mg).
Ignore friction and air resistance.
The vectors v (velocity) and a (total acceleration) have an angle ◊ between them, which
changes as the ball moves.
Check all the answers which are true statements. There may be more than one correct
answer!
when the ball is on the way up the loop, 0 > 90°º
the magnitude of a is always smaller than g, no matter how fast the ball moves
0 = 90° at the "side" points (halfway up the loop)
at the bottom of the loop, Ntrack is stronger than mg
the ball falls off the track if Ntrack
= 0
An Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. The masses have the values M(1): 27.0Kg and m(2)= 11.0Kg. Assume that the rope and pulley are massless and that there is no friction in the pulley.
What is the magnitude of the masses' acceleration a?
What is the magnitude of the tension T in the rope?
A tourist looks up at a tall obelisk and desires to determine the height of this object. He estimates that he is 278 meters from the base of the obelisk and the angle from the horizontal is 52.1 degrees. At that moment, a bird drops a twig from the top of the obelisk. How long, in seconds, does it take for the twig to fall to the ground? Assume no initial downward velocity and no drag.

When the van goes straight ahead at a speed of 20.1 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 140 m), the block swings toward the outside of the curve. Then the string makes an angle θ with the vertical.

The force of tension in each strand pulls at the junction. The net force at the junction is zero. In other words, the resultant of all three force vectors is zero at the junction. The gravitational force on the spider makes it exert a downward force of 0.15 N on the junction. The two sloping strands are perpendicular to each other. We have chosen the x and y axes to be along those strands as shown. The force of the right strand on the junction has magnitude Tx force of the left strand on the junction has unknown magnitude T,y. a) Calculate Ty. b) Calculate the angle between the x axis and the horizontal direction. Hint: The SI unit of force is the newton, which is abbreviated as N. You must consider three force vectors. The x components of all three vectors must add to zero, and the y components must also add to zero. Note that the coordinate system is "rotated" which is Tx Ty 0.127 Ν.

The coefficient of static friction between the box and the truck bed is Usb=0.50, the coefficient of rolling friction between the truck's tires and the road is Urt=0.03. The truck comes to an unbanked curve in the road having a 40m radius. What is the maximum speed with which the truck can take the curve without damaging the wine glasses? Note that in order for the wine glasses to not be damaged, the box they're in should not slide on the truck bed and the truck itself should not slide on the road while taking the curve.arrow_forward
