In a match, a toddler throws straight down his favorite 1.5 kg toy with an preliminary velocity of two.9 m/s. What is the magnitude of the change in velocity of the toy from t = zero.25 seconds to t = zero.47 seconds?A unicorn working on a seaside at 7 m/s modifications tempo at a unbroken cost of 1.2 m/s2 over a interval of two seconds. What distance did the unicorn journey all through this course of?An individual pulls a 5.Three-kg sled 51 meters alongside an angled hill with an influence of 36 N, which elevates the particular person 29 meters above the underside of the hill. The particular person then hops on his sled and slides from rest to the underside of the hill once more alongside his 51 meter path, all through which a 295 N frictional energy acts upon his sled. How so much work in Joules does the particular person do in opposition to friction in pulling the sled up the hill?A baseball pitcher throws a 148 g baseball at a velocity of 28 m/s within the route of residence plate. The batter hits the ball, and the speed of the ball coming off the bat is 48 m/s within the different means of the speed of the pitch. The bat is in contact with the ball for zero.002 seconds. What is the magnitude in Newtons of the frequent energy utilized to the ball?A meterstick is balanced on a fulcrum at its coronary heart. Then a 370 N weight is positioned 15 cm to the left of coronary heart. What variety of cm to the appropriate of coronary heart would a 180 N weight must be positioned with a view to stability the system?A motor spins a disk (Idisk = 24.4 kg*m2) with a torque of 38 N*m, and a 18 N frictional energy acts on the disk at a radius of 1.Three m. Hooked as much as the disk at a radius of two.4 m is a 18 kg mass. What is the magnitude of the angular acceleration in rad/s2 of the system?
