- 2.) A 200-gram ball is whirled around in a horizontal circle at the end of a string 1000cm long. What is the highest speed the object can have I'd the string has a breaking point of 4N 3.) A 1000-g ball is tied to a strong 60cm long and is whirled in a vertical circle at 1 revolution per second. If the tension at the highest point is zero, what is the speed of the body at the highest point? 4.) A body is moving along a circular path of radius 2.86m. If the centripetal force on the body is three times it weight, find period of the motion. 5. A curve along the highway is to be designed for cars moving at 100kilometers per hour.

As the statue slides down a ramp inclined at an angle θ=40∘θ=40∘, the curator pushes up, parallel to the ramp's surface, so that the crate does not accelerate. The statue slides a distance d=4.0m d=4.0m down the ramp, as shown in the figure, and the coefficient of kinetic friction μkμk between the crate and the ramp is 0.580.58.

Provide your answer in Cartesian vector form.How fast would you need to fire a 80 g Hot Wheels car down a straight track in order for it to successfully coast through a circular vertical loop of track with a radius of 30 cm? Draw a diagram and construct a force balance to determine your answer?Using a simple pulley and rope system, a т, crewman on an Arctic expedition is trying to frictionless lower a crate of mass mị 5.13 kg to the bottom of a steep ravine of height H 25.4 m. The 60.9 kg is walking while crewman of mass m2 т holding the rope, being careful to lower the crate at a constant speed of vo Н 1.50 m/s. Unfortunately, when the crate reaches a point h = 14.1 m above the ground, the crewman steps on a slick patch of ice and slips. The crate immediately accelerates toward the ground, dragging the hapless crewman across the ice and figure not to scale toward the edge of the cliff. Assuming the ice is perfectly slick, so that there is no friction between the crewman and the ice once he slips and falls down, at what speed vị will the crate hit the ground? Assume also that the rope is long enough to allow the crate to hit the ground before the crewman slides over the side of the cliff, and that the pulley is frictionless. m/s At what speed vz will the crewman hit the…

- 2. Consider the following arrangement of masses: Mass 1 is connected to mass 2 by a very light string and moves over a frictionless pulley so that both masses move with the same speed and move the same distances (m₂ to the right a distance d and m₁ down a distance d). Assume m₁ 15 kg, m₂ 15 kg, and the coefficient of kinetic friction between m₂ and the table is k = 0.73. Let the masses start with an initial speed of 1.00 m/s. What is their speed after moving 1.00 cm (d = 0.0100 m)? - mq - -25 ms m1There is a mortar that is firing on soldiers who are approaching up the hill towards the mortar.
