2. A raindrop falls into a puddle, creating a circular ripple. The radius of the ripple grows at a steady rate of 7cm/s If the origin is used as the location where the raindrop hits the puddl determine the equation that models the ripple exactly 28 seconds after the raindrop hits th puddle.A4.0 a block is elebloc down a frictionless inclined plane as shown. What is th e accele con of the block? 3. 0.559(D) 49 N 3. A 4.0 kg block is sliding down a frictionless inclined plane as shown . What is the acceleration of the block? (A) 2.5m/s^2 (B) 5.5m/s^2 (C) 6.6m/s^2 (D) 8.1m/s^2 O. 559/9What force F, applied parallel to the incline would make the 15 kg block move up the incline at a constant speed? (A) 30 N (B) 34 N (C) 64 N (D) 95 N19. A student on a bicycle decided to determine his acceleration when coasting down a steep hill.The student started from a full stop and reached a velocity of 8.75m/s in 3.8 s. What was his average acceleration?Assume that downhill is the positive direction. 20. A car enters a highway travelling 14m/s[N] . After 5.5 s. the car reaches a velocity of 28m/s[N] .
