Applying newton's law on the system in horizontal directionF=(M+m)a. Now consider the equilibrium of block B w.r.t. block M F^2=(mg)^2=(m(F)/(m+M))^2 F^2=(m^2g^2)/(1-(m^2)/((m+M)^2)),F=(mg)/(sqrt(1-((m)/(m+M))^2))
A block of mass 2 kg is pulled with a force of 10 N on a frictionless surface. Calculate the acceleration of the block.Good luck with your exam preparation! 相关知识点: 试题来源: 解析 5 m/s² 根据牛顿第二定律,物体的加速度与作用力成正比,与质量成反比,即公式为 \(a = \frac{F}...
Step 1: Understand the Forces Acting on the Block- We have a block of mass m placed on a horizontal surface.- An external force F is applied to the block, which increases linearly with time. We can express this as F=k⋅t, where k is a constant.- The friction force f acting on...
CWhen a constan force E is applied to the stationary object and yet it accelerates constantl means that Fis in the direction of the motion Only option C gives the unit of work done, which has the same units as kinetic energy By the work energy theorem, the net work done on the object...
on the rough, sloping side of a triangular block of massMwhich itself rests on a horizontal frictionless table as shown in Fig. 5-41. If the coefficient of static friction isμ,determine the minimum horizontal forceFapplied toMthat will cause the small blockmt...
Lowered the center of mass of the animal trailer to make them tip over less (bear in mind, turning aggressively at 40MPH will still make them flip over!). Force towed trailers to be rendered when inside the car. Added the OutputFlag "IsBlunt" to handle cases where we want the items ...
13 A constant force F is applied to a stationary object of mass m on a frictionless surface. A constant acceleration increases the velocity of the object to some value v in a time t. It covers a distance s during this time.Which value of the kinetic energy is given to the object? A...
The archetype shown in Fig.1a comprises a mass block, a vertical supporting spring, and a pair of horizontal springs. The movement of the mass block is restricted to the vertical direction, and all the mass,m, is lumped at the geometric centre. The deformation of each the horizontal spring...
