he FBD of the block should have looked like this.       1.    A contestant in a winter sporting event pushes a block of ice  of mass m across a frozen lake as shown in the figure. The coefficient of static friction between the block and ice is μs, and the coefficient of kinetic friction is μk. θ is the angle the force makes with the x-axis. In this part, we are going to set-up Newton's second Law equations for the cases(1) when the ice block just starts moving, and(2) when it is accelerating to the right with an acceleration a. All answers are symbolic. ALL ANSWERS ARE CASE-SENSITIVE.         Subpart 1: Newton's Second Law along the y-axis  (i) Write Newton's Second Law along the y-axis by adding all forces in the y-direction taking into account their signs (forces pointing upwards are positive and downward are negative) in terms of the normal force N, weight mg, F and θ. In both scenarios, there is no acceleration along the y-direction, therefore, ay=0.…

A block is sliding UP an incline because someone gave it a push a moment ago. The slope of the incline is 10%. The friction coefficient between the block and incline is u the incline is considered the +x direction, what is the acceleration of the block? Please draw a diagram 0.20. If the direction down with all relevant forces.

A block is being pulled by the string as shown below. The string has a tension T and makes an angle with the horizontal. A student claims that the kinetic friction is given by μmg where m is the mass of the block and uk is the coefficient of kinetic friction. Is or isn't this expression correct? Explain your reasoning.

Figure shows the velocity graph of a 65 kg student in an elevator. What is the student's apparent weight (magnitude only) at t = 7.0 s, in Newtons? Use g = 10.0 m/s². (Hint: What is the net force?) 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. Vy (m/s) 8- 4- (s) 10 4. 6. 8.

A box of mass 5.9 kg is sliding down a ramp, as shown in the picture. The coefficient of kinetic friction between the ramp and the box is 0.4, while the angle of the ramp with the ground is 30°.     What is the size of the friction force?

A block is pushed up a ramp and is observed to accelerate up the block as is shown in the figure below.  The friction coefficient between the block and the ramp is mu. Write an expression for the acceleration of the block in terms of F, theta, m, g and mu.
