The parachute on a drag racing car deploys at the end of a run. If the car has a mass of 1,000 kg and the car is moving 40 m/s, what magnitude force (in N) is necessary to stop the car in a distance of 860 m? (Note: First, find the acceleration of the car using Unit One material, then use this to compute the force. Since the question asks for the magnitude, input a positive answer.)

A cabinet of mass 3.7 kg is at rest on a ramp as shown. What is the magnitude of the friction force on the cabinet, in Newtons? The coefficients of friction between the cabinet and ramp are Ps = 0.850 and uk = 0.750. Use g = 10 m/s2. (Hint: what type of friction is it?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 30.0

Consider an object of mass m being pushed up a frictionless incline of angle theta by a force F parallel to the ground (not the incline). If the object is moving at a constant velocity, the expression for F in terms of m, g (the acceleration due to gravity near the earth's surface, leave it as a letter), and theta is______ (The outcome that I found was F=MgTan(theta) The “not the incline” it confuses me

Four forces act on an object, given by  A = 38.3 N east, B = 45.3 N north, C = 70.7 N west, and D = 88.7 N south.  (Assume east and north are directed along the +x-axis and +y-axis, respectively.) (a) What is the magnitude of the net force (in N) on the object?   (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)

Calculate the tension in a vertical strand of spider web if a spider of mass 2.16 kg hangs motionless on it. Put your answer in scientific notation rounded to two significant figures. Take the acceleration due to gravity to be g = 9.8 m/s2. Include your unit. Format your answer as (coefficients)e(exponent). For example, should be written as 5.1e-2.

Three stacked blocks have a downward force F' exerted on them as shown: Assume the system is at rest (such as blocks stacked on a stationary table). If m = 6.5 kg and F' = 9.9 N, what is the normal force exerted on the 5m block by the 8m block? Express your answer in N, to at least one digit after the decimal point.

Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s NOT cm/s). Answer must be in Standard Form Scientific Notation
