A woman pushes her new John Deere walk behind mower to the right as she approaches her garage. If she pushes the 55-kg mower with a force of 120 N directed downward at an angle of 40 degrees, what is the acceleration if there is a frictional force of 42 N resisting its motion? What is the normal force acting on the mower?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Awhite-blue star is hotter than a red star. select the best answer from the choices provided true or false

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
