The spring in a toy rocket launcher has a spring constant of 80 N/m. How far must you compress the spring to cause it to exert a force of 2 N

What are the SI base units of the newton?

What is the symbol for displacement

A driver wearing a seat beat decelerates at roughly the same rate as the car it self. Since many modern cars have a "crumble zone" built into the front of the car, let us assume that the car decelerates of a distance of 0.9 m.

Why is it sensible on diagrams to represent a force by an arrow?

What is impulse, and what are the formulas?

An archer defending a castle is on a 15.5 m high wall. He shoots an arrow straight down at 22.8 m/s. How much time does it take to reach the ground?

Four potential forces can act on the ball Which combination of forces will keep the ball in static equilibrium? The length of the arrows represents the magnitude of the force A and B A and C B and D 8. Cand D Submit Force, Mass, and Motion

The resultant of a 50N force acting on an object to the right and a 20N force acting on the object to the left is what

A student conducts and investigation to determine a ball's mass, displacement, velocity and acceleration. (A) Identify each of the following as wither a vector or scalar quantity: Mass, Displacement, Velocity & Acceleration.

A ball is rolling down a hill at + 1.0 m/s, The ball is uniformly accelerating at +4.9 m/s?, What will the ball's velocity be 4.0 s later? +8.9 x 100° m/s +2.0 x 10^1 m/s +2.1 x 10^1 m/s -1.9 x 10^1 m/s
