one of your classmate has a friend with a boat. here is your classmate on water-skis being towed. in the absence of friction your classmate (m=62kg) would accelerate at 2.23m/s^2. a. determine the tension in the tow rope for there ideal conditions. (A FBD of the skier is expected) b. in the actual case friction with the water is the primary non-ideal condition. as a result of this your classmate reaches a top speed of 14.8m/s after 8.2s beginning from rest. what is the friction force of the water?
What is the speed of the block of clay right after the collision. What impulse does the clay exert on the block.
At time t=0 a grinding wheel has an angular velocity of 28.0 rad/sec. It has the constant angular acceleration of 35.0 rad/sec^2 until a circuit breaker trips at time t=1.80. From then on, the wheel turns through an angle of 433 as it coasts to the s..
A ball is thrown vertically upward with a speed of 1.63m/s from a point 4.21m above the ground. What is the time at which it will reach the ground.
If 20 grams of hot water at 80°C is poured into a cavity in a very large block of ice at 0°C, what will be the final temperature of the water in the cavity? How much ice should melt in order to cool the hot water down to this temerature.
What is water speed along the boat during the vertical cross
A particle moving along the x axis in simple harmonic motion starts from its equilibrium position, the origin, at t = 0 and moves to the right. The amplitude of its motion is 1.70 cm and the frequency is 1.30 Hz.
A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
The lows note emitted by stretched string has a frequency of 50Hz.how many outcome are possible between 40Hz and 170Hz.
David is driving a steady 26 when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.8 at instant when David passes.
A projectile is launched at ground level with an initial speed of 50.0 m/s at an angle of 30.0º above the horizontal. It strikes a target above the ground 3.00 seconds later. What are the x and y distances from where the projectile was launched to..
What is the distance, measured along the screen, between this bright fringe and bright fringe corresponding to m = 3.
Block 1, of mass m_1 = 0.500 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2. Suppose that the blocks accelerate with an acceleration of magnitude a = 0.550 m/s^2 and that coefficient of kinetic friction b..
