The mass m2 is hanging above the ground and pulling another mass over a 57.27 degree ramp with acceleration 0.5 m/s2. calculate mu_k. Your Answer: AnswerV F Resolve the force F into components along the u and v axes, and determine the magnitudes of these components. Given that F = 35 N, a = 16° , and ß = 32°, the magnitude along u is (round to one decimal place) : N the magnitude along v is (round to one decimal place) : N

Find the magnitude, in newtons, of the total force on the Achilles tendon.1. A golf ball is hit from ground level with initial velocity given x(t)= 3 m/s(t) in a direction that is due east and at an angle theta above the horizontal. Neglecting air resistance, use Newton's second law to find the position as a function of time, using coordinates with x measured east and y north. Find the time for the golf ball to return to the ground and how far it travels in that time.A 20-kg particle moves with this trajectory: r ( t ) = − 40 t ȷ ^ + 25 t ı ^ + ( 5 ı ^ − 8 ȷ ^ ) e − 5 t Calculate the force on the particle.
