Question

can u slove it plz

An object is on a frictionless inclined plane. The plane is inclined at an angle of 30 degree with What is the object's acceleration in terms of g, where g = 9.80 m/s2? An object moves with a constant speed of 20 m/s on a circular track of radius 100 m. What acceleration of the object? 10-N force is needed to move an object with a constant velocity of 5.0 m/s. What is the object? golf ball of mass 0.045 kg is struck with a club with a force of 580 N. If the club was in 11 for 3.5 ms, calculate the speed the ball takes off with. ice skater has a moment of inertia of 5.0 kg m2 when her arms are outstretched. At this spinning at 3.0 revolutions per second (rps). If she pulls in her arms and decreases her month 1 kg m2, how fast will she be spinning?

Explanation / Answer

1) a= g sin theta = g sin 30 = 0.5g

2) v = 20 and r = 100

w = v/r = 0.2 rad/s^2

normal acceleration = v^2 /r = 4 or w^2*r = 4
