a circular track has a circumference of 1570m with AB as one of its diameter . a scooterist moves from A to B along the circular path with a uniform speed of 5 m/s find the a) distance covered b) displacement c)time taken for the scooterist to reach from A to B

A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure. The length of the arc ABC is 202 m, and the car completes the turn in 40.0 s.

(a) Determine the car's speed.

(b) What is the magnitude and direction of the acceleration when the car is at point B?

neglecting air resistance, if a ball thrown 4.5 m/s horizontally from a 94 m cliff, how far has the ball fallen after 2.7 seconds?

a car travels at a constant speed on a flat circular track. which factor, when doubled, either mass of car, weight of car, radius of track, or velocity of car, will decrease the centripetal force on the car?

what does the tangent at a point to the position time graph for an object in non-uniform motion along a straight line represents

determine the magnitude and direction of the resultant of the following displacements: 5m east, 8m 45 degrees North of east, 3m 60 degrees south of west, and 7m south.

A particle is projected from a point A at an angle(Q) with the horizontal. At B it moves at right angle to its initial direction. Find time of Flight from A to B.

two persons in the field who are 120 metres apart. one of them kicks the ball at a speed of 30m/s at an angle of 38 degrees. what is the velocity the second person should use in order to find the ball when its just meeting the ground.

thank you

A car is moving on a lvel road. a pendulum suspended from the ceiling makes an angle of 10 degre with the verticle. find the acc. of car. g=10m/s2

Suppose the motion of the particle is described by the equation: x=a+bt2, where a=20cm and b=4cm.s-2. a) Find the displacement of the particle in the time interval between t1 =2s and t2 =5s. b) Find the average velocity in this time interval. C) Find the instantaneous velocity at time t1 =2s.
