(a) Find the cat's initial velocity, initial position, and initial acceleration. (b) At what time is the velocity of the cat zero? (c) How long after starting does it take the cat to return to its starting point?

At time t = 0, a particle is at rest in the x-y plane at the coordinates (xo, Yo) = (9, 0) in. If the particle is then subjected to the acceleration components ax = 0.64 - 0.33t in. /sec² and ay = 0.15t - 0.03t² in. /sec², determine the coordinates of the particle position when t = 6 sec. You might consider plotting the path of the particle during this time period. Answer: (x, y) = (i " )in.

C and D please

answer D only v(0)=5fps

Question 15 of 20 A train has a length of 93.8 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 16.0s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 36.0 s, the car is again at the rear of the train. Find the magnitudes of (a) the car's velocity and (b) the train's acceleration. (a) Number i > (b) Number i Units Units UNITS CHOICES: no units, s, m, m/s, m/s^2 L

Suppose a fly orbits you (on the horizontal plane) with a constant orbital radius of 5 meters and subject to a time-varying (tangential) acceleration given by the expression a ( t ) =1+t with an initial speed of 2 m/s. Since the fly remains a constant distance away from you, you cannot use your flyswatter the way you would like to. Suppose that you can throw your flyswatter with an initial speed of 15 m/s in any direction you want. If you throw at t=0, how, exactly, should you throw your flyswatter to hit the fly? (Give both the angle above the horizontal to throw your flyswatter –and- at what angle ahead of the fly to throw it). ..

7. A ball attached to a string of length 0.25 meters is whirled around in a circular path. It experiences a centripetal acceleration of 40 m/s². a. What is the tangential velocity of the ball? b. How long does the ball take to make one complete revolution?

Let's see what you got

I need a clear answer by hand, not by keyboard and fast answer within 20 minutes. Thank you | dybala The system is initially at rest with no slack in the cable, and the mass and friction of the pulleys are negligible. Determine the following: 1- The acceleration of the block if (a) T = 20 N and (b) T= = 30 N. 2- The velocity of the block in 4 seconds if T = 30 N. Hs=0.50 H=0.40) 15 kg 30° T
