1) An object's original position is 30 meters at an angle of 150 degrees and final position is 30 meters at 70 degrees. The object traveling at constant speed in a circular arc clockwise and makes the journey in 12 seconds.

a) Find the Displacement vector

b) find the total Distance traveled.

c)find the avg Velocity vector, avg Speed, and instantaneous Speed.

d) find the avg Acceleration vector and instantaneous Acceleration vector. Show that the avg Acceleration vector points towards the center when placed at the midpoint of the arc!

A cannon is elevated at an angle of 30 degrees and fires a cannonball with a speed "v1". The Cannon is on top of a cliff with a height of "h". Given v1 and h, determine: a) The speed of the cannoball when it is at its maximum height. b) The speed of the cannonball just before hitting the ground. c) The angle the cannonball's velocity makes with the horizontal just before hitting the ground. d) The horizontal distance the...

a) A treasure map gives the following directions: (1) Walk fifty meters at 30 degrees north or east from the old oak tree. (2) Turn 45 degrees to your left (you should now be facing 75degrees north of east) and walk another fifty meters. You will find the treasure buried under a rock. What straight-line path would take you directly from the old oak tree to the rock with the treasure buried under it? b) You followed the first direction...

A 4.0-kg block is on an incline plane of 30 degrees angle with respect to horizontal. a)What is the minimum coefficient of static friction (μs)min is need to prevent it from sliding down? b) If the surface μs is 0.30, less than (μs)min now, how much force(F) is needed to apply to the block horizontally to prevent it from sliding down?c) If F is doubled, what’s the acceleration of the block up the incline? Assume the coefficient of kinetic friction...

(1 point) Suppose a pendulum with length L (meters) has angle θ (radians) from the vertical. It can be shown that θ as a function of time satisfies the differential equation: ((d^2)θ)/(dt^2))+(g/L)sinθ=0 where g=9.8/sec is the acceleration due to gravity. For small values of θ we can use the approximation sin(θ)∼θ, and with that substitution, the differential equation becomes linear. A. Determine the equation of motion of a pendulum with length 0.5 meters and initial angle 0.5 radians and initial...
