Suddenly the driver starts to decrease the speed at a rate 1.370 m/s2. the acceleration just after braking is Select one: a. 0.00 b. 8.77 c. 9.86 d. 9.32 e. 11.23 the speed at t-4 s is Select one: a. 10.96 b. 5.70 c. 3.51 d. 19.51 e. 4.16 the acceleration at t=4s is Select...
please, I need a right answres ASAP.
because one of the experts solved it wrong...
there is no wrong in the questions!!!!
not most of them are not in the choices !!!!!

7. [2 points] A particle is moving at a constant speed in a circular path centered at the origin on an xy coordinate system. At one point (x=4m, y=0), the particle has a velocity of 5ġ m/s. a. State whether the particle is moving clockwise or counter-clockwise on the circular track. b. What is the constant speed of the particle throughout its circular trajectory? c. What is the acceleration (expressed as a vector) of the particle when it is at...
1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...

2. The amusement park ride consists of a 200-kg car and passenger that are traveling at 3 m/s along a circular path having a radius of 8 m (horizontal plane) If at t 0, the cable OA is pulled in toward O at 0.5 m/s, determine: a. Is energy conserved? why? (5%). b. Is angular momentum about point O conserved? why? (596). C. The speed of the car when t-4 s (10%). d. work done to pull...
1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
