Two blocks are connected by a string, as shown in the figure (Figure 1). The smooth inclined surface makes an angle of 35 with the horizontal, and the block on the incline has a mass of 5.7 kg. The mass of the hanging block is m -2.8 kg Figure 1 01 1 5.7 kg 1m 35°

Passengers riding in the Great Six Flags Air Racer are spun around a tall steel tower. At top speed, the planes fly at a 56-degree bank approximately 46 m from the tower. In this position, the support chains make an angle of 56 degrees with the vertical. Calculate the speed of the planes.

(1) The drill exerts a 32 N-m couple on the plywood sheet during operation. What are the minimum opposite, equal and parallel forces F, that must be applied at points B and C to keep the plywood from spinning? 32 Νm B. 240 mm 450 mm Fig. P3.69

A bucket is hanging from a horizontally moving crane. Calculate the maximum allowable speed (m/s) of crane if L =6.07m and θ is limited to 22.3 degrees when the crane suddenly stops. Round off only on final answer expressed in 3 decimal places.

A bicycle travels 6.70 km due east in 0.240 h, then 14.40 km at 15.0° east of north in 0.310 h, and finally another 6.70 km due east in 0.240 h to reach its destination. The time lost in turning is negligible. Assume that east is in the +x-direction and north is in the +y-direction. What is the magnitude of the average velocity for the entire trip? What is the direction of the average velocity for the entire trip? Enter the answer as an angle in degrees north of east.

A wrench is dropped from the top of a tall tower. It takes 3.07 s to reach the ground. How tall is the tower, in meters? Assume the wrench’s initial velocity is zero, use 9.80 m/s2 as the acceleration due to gravity, and assume air drag does not matter.

The shot put is a track-and-field event in which athletes throw a heavy ball - the shot - as far as possible. The best athletes can throw the shot as far as 23 m . Athletes who use the "glide" technique push the shot outward in a reasonably straight line, accelerating it over a distance of about 2.0 m . What acceleration do they provide to the shot as they push on it? Assume that the shot is launched at an angle of 37 degrees, a reasonable value for an excellent throw. You can assume that the shot lands at the same height from which it is thrown; this simplifies the calculation considerably, and makes only a small difference in the final result.

An old car tire (I=MR2)isplaced at a vertical height of 2.5 m on a slopethat makes a 18°angle with the horizontal.It is released from rest and rolls without slipping to the bottom of the slope. What is the tire’s velocity at the bottom? Also calculate acceleration.

T3.23 Please help me answer this physics question.

At a certain instant, the magnitude of velocity and acceleration of a point shown below are V = 10.0 m/s and a = 46.9 m/s?. The acceleration is directed at an angle of 0 = 34.3° as shown in the figure. At this instant, find the radius of curvature of the path in meters. V m/s a m/s? -----
