Answer #1

According to the Newton 1st law of motion

Statement: Every Object is remain in it state rest or motion until it's experience by another external force.

Solution: So here spaceship having constant acceleration. But spaceship accelerate means its should have experience the external force. It's means their is acceleration their must force present(F=ma) so we can say that there must external constant force required to maintain const acceleration. All Newton laws should valid.

Centripetal Acceleration: A car moving with a constant speed of 80 km/h enters a circular, flat curve with a radius of curvature of 0.50 km.  If the friction between the road and the car’s tires can support a centripetal acceleration of 1.20 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road? Perform calculations to justify your answer. Be sure to perform all the necessary dimensional conversions to mks units.

A cart of mass m1(pictured) is free to move nearly frictionless up a ramp at angle θ. A small mass m2 hangs from a string that runs over a pulley and connects to m1. We will determine the acceleration of the cart m1 over a known distance x,then plot the acceleration of m1 as a function of the hanging mass m2. a) The hanging mass will create a constant pulling force to accelerate the cart up the ramp. Using Newton’s...

In this example we will calculate the coefficients of static and kinetic friction using two equations along with Newton’s second law of motion. Suppose that a delivery company has just unloaded a 500 N crate full of home exercise equipment in your level driveway. You find that to get it started moving toward your garage, you have to pull with a horizontal force of magnitude 230 N. Once the crate “breaks loose” and starts to move, you can keep it...
