A garbage truck has a weight of 20500 lbs. Find its mass in kg and slugs

A force of 18 N is needed to start a box weighing 76 N sliding across the floor. What is the coefficient of friction?

Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor. (a) The 1800 kg tractor exerts a force of 2.00 x 104 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. If the acceleration is 0.120 m/s², what is the mass of the airplane in kilograms? kg (b) Calculate the force (in N) exerted by the tractor on the airplane, assuming 2100 N of the friction is experienced by the airplane. N

An astronaut (70.0 kg) is on a 15,000 kg rocket. It takes off from the launchpad onEarth, with the engines providing 200,000 N of thrust.What is the astronaut’s apparent weight as it is taking off?

Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor. (a) The 1800 kg tractor exerts a force of 1.80 × 104 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. If the acceleration is 0.170 m/s2, what is the mass of the airplane in kilograms? kg (b) Calculate the force (in N) exerted by the tractor on the airplane, assuming 2250 N of the friction is experienced by the airplane. N

A bucket that has a mass of 25 kg when filled with sand need to be lifted to the top of a 10 meter tall building. You have a rope that has a mass of 0.4 kg/m that must be secured to the bucket. It takes 1 meter of rope to secure the bucket. Once the bucket reaches the top of the building it only has mass 14 kg because there was a hole in the bottom and sand was leaking out at a constant rate while it was being lifted to the top of the building. Find the work done lifting the bucket (sand and rope) to the top of the building.

What is the weight of(a) a 5.2 kg package of nails in Newtons?

A constant net force of 300N is applied to accelerate a cart in a frictionless surface from rest to a velocity of 30 m/s in 5s. What is the mass of the cart? 2. A 0.15 - kg baseball approaches a baseball bat at 30 m/s. If it is in contact with the baseball bat for 0.003 s, what is the average contact force between the ball and the racket? Ignore the air resistance.

A force of 35 N pushes three boxes along a horizontal surface. Find the contact force between 2 kg box and 1 kg box. (ans:5N)

The gymnast weighs 427 N and is suspended motionless from two spring scales, each of which has negligible weight. What do the two spring scales read?
