- Question 23 Two frisky otters slide down frictionless hillsides of the same height but different slopes. The slope of the hill of otter 1 is 30°, while the slope of the hill of otter 2 is 60°. If both start from rest, which otter is moving faster when she reaches the bottom of her hill? O The otter that took the shorter time is moving faster. O Otter 2 is moving faster. O The heavier otter is moving faster, no matter which hill she used. O Otter 1 is moving faster. O Both otters have the same speed at the bottom.Question 2 Figure 2 shows a 2-story steel frame with h = 4 m and b = 6 m, determine the equivalent horizontal forces (EHF) for both floors under the following actions: Dead load = 20 kN/m Imposed load = 12 kN/m Students can make their own rational assumptions for any information which they think is required but not provided. Clear state the assumptions and the corresponding justifications. W W b Figure 2 hQUESTION 28 You push a 80-kg file cabinet to the right on a frictionless horizontal surface with a force of 175 N from rest, the cabinet moves a distance of 12 m. What is the final speed of the cabinet, in m/s? 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.
- A block of mass m = 1.34 kg (Block 1) at rest at Point A on an arc of smooth circular surface of radius L = 30 m. Another block of mass M = 3.22 kg (Block 2) is at the bottom of the arc as shown in Fig.6. The line between the center of the arc and Point A and the line between the center of the arc and Point B make an angle 0 = 35 deg. If Block 1 is released and slides on the arc and hits Block 2, Block 1 stops at Point B and Block 2 starts to move along the arc. What is the velocity of Block B right after the collision in m/s. Keep three significant figures for the answer. g= 9.80 m/s. There is no friction.a. Calculate the force (in N) needed to bring a 950 kg car to rest from a speed of 80.0 km/h in a distance of 110 m (a fairly typical distance for a non-panic stop). b. Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a). force in (b)/force in (a)=6. Two packages that start sliding down a 20° ramp from rest a distance d = 4.30 m. For package A: Ma = 5.00 kg and ukA = 0.30. %3D For package B: mB = 7.00 kg and ukB = 0.20. Find the speed of both packages when they reach the bottom. 20°

Determine the r and y components of each of the force vectors above. 25 NMove over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the Oyoy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 106.0 kg and is shaped like a cylinder of radius R = 0.835 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0830 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius = r Mass = M The FORMULA for the moment of Inertia: I = V(y=0)=? We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 77.5 kg is using the Oyoy and…
