- Ramp A block is given an initial velocity of 5.00 m/s up a frictionlessincline with an angle of 20.0° from horizontal. How far up the inclinedoes the block slide before turning around?Please answer it within 30 minutes.I will upvote! Problem: With ball initial velocity of 40m/sCoefficient of kinetic friction between ball and ground is 0.110.How fast is the ball still traveling when it reaches net distance of 18m away?Assume the ball is still in motion on the ground the entire time.Please asap
- 10. If two objects are dropped in an environment without air resistance, what will occur? Both of the objects will fall with constant velocity O The lighter of the two objects will fall faster than the heavier. O The heavier of the two objects will fall faster than the lighter. O The objects will accelerate downward at the same rate.The Car is thrown from a building that is 45M high.Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the Oyoy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 106.0 kg and is shaped like a cylinder of radius R = 0.835 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0830 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius = r Mass = M The FORMULA for the moment of Inertia: I = V(y=0)=? We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 77.5 kg is using the Oyoy and…
- 4. Show that the acceleration of any object down an incline where friction behaves simply (that is, where F* = Hk FN) is a = g(sin 0 – Hk Cos 0). Note that the acceleration is independent of mass and reduces to a = g sin ở when friction becomes negligibly small (4k = 0).3. A base year student with a mass of 85 kg slides on a surfboard down the stairs in NI:0E11 with a constant speed of 3.0 m/s. The stairs have an angle of 15.0 degrees to the ground. (a) Free the surfer (ie the surfer and the teacher as a unit). (b) Calculate the frictional force.A stray dog catcher drives 34km east, picks up some dogs, then drives 10km west to drop them off before continuing east for 21km. 30N of force is being applied constantly parallel to the dog catcher's motion. Solve for the work the dog catcher has accomplished.
