- Consider a human who weighs 862 N on Earth. What is the person's mass on Earth? And what is the same person's mass on Mars, where the acceleration due to gravity is 3.7 m/s2?Find the acceleration of the masses shown. Assume the table is frictionless and the masses move freely. m1=1.00 kg, m2=2.00 kg, m3=3.00A student has a mass of 25 kg. If he stands on a scale in an elevator that is accelerating downward at 2.0 m/s/s, what will be his apparent weight?
- A ball of mass 5 kg experiences a change in its velocity from 2 m/s to 4 m/s within 20 s, under the influence of a constant force. However, the direction the ball is moving in does not change. Find the direction and magnitude of this force.A student weighs 200 N. If he is in an elevator that is accelerating upward at 2.00 m/s/s, what will be his apparent weight?An object is propelled along a straight-line path in space by a force. If the mass of the object somehow becomes twice as much,its acceleration A. quadruples B. halves C. doubles D. always the same
- When someone lands from jumping in the air, is the normal force on the person greater than, less than or equal to the force of gravity on the person?The acceleration of gravity on the surface of the moon is approximately 1/6 of that at the surface of the Earth. What is the mass of an astronaut standing on the moon whose mass on Earth is 48 kg? Express your answer in kg.If the weight of an astronaut plus their space suit on the moon is only 255 N. With the W = 255 N. How much would they weigh on Earth, in newtons assuming the acceleration due to gravity on the moon is 1.67 meters per squared second? In this context, what would the mass of the astronaut in their space suite be both on the Moon and on Earth in kilograms?
