Lifting a 35‑kilogram object vertically at aĬonstant speed of 5.0 meters per second? 1,700W Which pair of quantities represent scalar The block's acceleration is Zero What is the rate at which work is done in On the surface of planet X is 4.0 m/s^2 If a block is in equilibrium, the magnitude of Magnitude of the acceleration due to gravity His gravitational potential energy decreases and his kinetic energy remains the same When 150 joules of work is done on a system by an external force of 15 newtons in 20 seconds, the total energy of that system increases by 1.5x10^2 On the surface of planet X, a body with a mass ![]() 2.6 As a student walks downhill at constant speed, ![]() After the spring is released, the speed of cart B is 6.0 meters per second, as represented When a compressed spring attached to one of the carts is released, the carts are Interval is 15 A 7.0‑kilogram cart, A, and a 3.0‑kilogram cart, B, are initially held together at rest on a horizontal,įrictionless surface. 2.0x10^2 What is the magnitude of the gravitationalĠ.425‑kilogram soccer balls when the distanceīetween their centers is 0.500 meter? 4.82 x 10^-11 The speed of a car is increased uniformly fromġ1 meters per second to 19 meters per second. What is the average power developed by theĬar engine while it is accelerating? 3. seconds it takes toĪccelerate the car along a horizontal surface. Strength near Earth's surface is represented by Fg/m A car engine supplies 2.0 × 10 joules ofĮnergy during the 10. Represents the directions of the velocity, v, andĪcceleration, a, of a toy car as it moves in aĬlockwise, horizontal, circular path at aĬonstant speed? 3 -The magnitude of the gravitational field The magnitude of the car's acceleration? 4.0 The diagram below represents a box slidingĭown an incline at constant velocity. The springĬonstant of this spring is 50 N/M Starting from rest, a car travels 18 meters as itĪccelerates uniformly for 3.0 seconds. The spring is stretched to a length of 0.60 meter when a 10.‑newton weight is hung motionless from one end. Interval? 2.5 m/s^2 A spring has an unstretched length ofĠ.40 meter.
