Find the acceleration of an object with 1 kg and 1 N.

A force of 20 N acts upon a 5 kg block. Calculate the acceleration of the object.

Aliya kicks a soccer ball with a mass of 0.5 kg. It accelerates with a rate of 5 m/s². What would be the force she used to kick it?

The mass of a young elephant is 100 kg. How much force would be required to accelerate the elephant at a rate of 3 m/s²?

Sophia, whose mass is 52 kg, experienced a net force of 1800 N at the bottom of a roller coaster loop during her school's physics field trip to the local amusement park. Determine Sophia's acceleration at this location.

An object is experiencing a constant acceleration of

2.11 m/s/s. It is being pushed along a horizontal surface by a 600-Newton force and experiences an opposing force of 475 Newtons. What is the mass of the object?

While skydiving, Dee Selerate opens her parachute and her 53.4-kg body immediately accelerates upward for an instant at 8.66 m/s/s. Determine the upward force experienced by Dee during this instant.

A rightward force is applied to a 6-kg object to move it across a rough surface at constant velocity. The object encounters 15 N of frictional force. What is the applied force on the object?

A 20 kg minifridge resting on the floor requires a 120 N horizontal force to move it from rest. What is the coefficient of static friction between the minifridge and the floor?

The coefficient of static friction between a television and oak table is 0.4. If the television's mass is 30 kg, how much force is required to begin moving the television to the left?

A 5 kg plate of brisket is sliding across a table. If the coefficient of kinetic friction between plate and table is 0.44, how much force must be applied to the plate for it to slide at a constant velocity across the table?
