object? A runner exerts a net force of 225 N to accelerate at a rate of 3.0 m/s2. What is the runner’s mass? What average net force is required to stop a 4 kg bowling ball in 0.5 s if it’s initially traveling at 10 m/s? A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink. A player applies a horizontal of 0.5 N to the puck. Find the speed and the traveled distance 5 s later. Mass and Weight: Class Work A woman weighs 580 N. What is her mass? Find the weight of a 2000 kg elephant. An astronaut has a mass of 85 kg. Calculate his weight on Earth and on the Earth’s moon (gmoon = 1.6 m/s2). Does his mass change when he goes from Earth to its moon? A car weighs 14500 N. What is its mass? Calculate the weight of a 4.5 kg rabbit. At the surface of Mars the acceleration due to gravity is 3.8 m/s2. A book weighs 34 N at the surface of the Earth. What is its mass on the earth’s surface? What are its mass and weight on Mars’s surface? Homework A boy weighs 270 N. What is his mass? Find the weight of a 60 kg table. A Martian weighs 17 N on the surface of Mars. Calculate his weight on Earth and on the Earth’s moon. Does his mass change along the flight from Mars to the Moon to the Earth?
