A 1 kg model rocket is launched at a 30 degree angle from the floor. The small rocket burns for 5.00 s and has a steady thrust of 20.0 N. What maximum altitude does the rocket reach and range of the...

A net force acts on mass m1 and creates an acceleration.A mass m2 is added to mass m1.The same net force acting on two mass together creates one-third the acceleration.Determine the ratio m2/m1

For each situation, determine whether the forces acting on a roller coaster are balanced or unbalanced and explain why using physics terms please:   The roller coaster moves at...

To slide a metal puck across a greased sheet of metal at constant speed requires a force of 0.525 N. If the force of gravity on the puck is 5.00 N, what is the coefficient of friction between the...

A car is travelling at 120 km/hr when it slams on the brakes. a. How long is the skid mark if the coefficient of friction is 0.62? (hint: convert km/hr to m/s) b. Explain why a more massive...
