In a fit, a toddler throws straight down his favorite 1.5 kg toy with an initial velocity of 2.9 m/s. What is the magnitude of the change in velocity of the toy from t = 0.25 seconds to t = 0.47 seconds?
A unicorn running on a beach at 7 m/s changes speed at a constant rate of 1.2 m/s2 over a period of 2 seconds. What distance did the unicorn travel during this process?
A man pulls a 5.3-kg sled 51 meters along an angled hill with a force of 36 N, which elevates the man 29 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 51 meter path, during which a 295 N frictional force acts upon his sled. How much work in Joules does the man do against friction in pulling the sled up the hill?
A baseball pitcher throws a 148 g baseball at a velocity of 28 m/s towards home plate. The batter hits the ball, and the velocity of the ball coming off the bat is 48 m/s in the opposite direction of the velocity of the pitch. The bat is in contact with the ball for 0.002 seconds. What is the magnitude in Newtons of the average force applied to the ball?
A meterstick is balanced on a fulcrum at its center. Then a 370 N weight is placed 15 cm to the left of center. How many cm to the right of center would a 180 N weight need to be placed in order to balance the system?
A motor spins a disk (Idisk = 24.4 kg*m2) with a torque of 38 N*m, and a 18 N frictional force acts on the disk at a radius of 1.3 m. Attached to the disk at a radius of 2.4 m is a 18 kg mass. What is the magnitude of the angular acceleration in rad/s2 of the system?
