the velocity v of a particle is given by v=1-4x where x is position.if the initial velocity of the particle is 2m/s,find an equation for x in terms of t.没有说是匀加速运动 相关知识点: 试题来源: 解析 这是道微分方程题目,应该这样做: 设x=f(t) f'(t)=v=1-x dx/dt=1-x...
D(v0+g+f) D(a2)+(g3)+(f4) The velocity of a particle isv=v0+gt+Ft2. Its position is x=0 at t=0, then its displacement after time (t=1) is : View Solution The velocity of a particle is given byv=u0+gt+12at2. If its position isx=0att=0, then what is its displacem...
1. Identify the given velocity function: The velocity of the particle is given by the equation: v(t)=4t2−4t+3(in m/s) 2. Differentiate the velocity function to find acceleration: Acceleration a(t) is defined as the derivative of velocity with respect to time: a(t)=dvdt We will ...
