Why does the momentum before a collision equal the momentum after a collision? a) because velocity is conserved b) because force times mass equals acceleration c) because momentum is conserved

Abird sitting high in a tree is an example of what type of wnergy

Astudent pushes on a 20.0 kg box with a force of 50 n at an angle of 30° below the horizontal. the box accelerates at a rate of 0.5 m/s2 across a horizontal floor. what is the value of the normal force on the box? 200 n 243 n 156 n 225 n

Me with this and you will be marked brainliest
