What is the weight of a/an 178 kg body in newtons? Consider the acceleration due to gravity to be .
A body of mass 30.6 kg was at rest on a smooth horizontal plane. A horizontal force 51 N acted on it for 5 seconds. Determine the body’s speed at the end of the 5 seconds.
A constant force acted on a body of mass 9 kg, such that its speed changed from 58 km/h to 66 km/h in a second. Calculate the magnitude of the force.
