In the one-dimensional motion of a particle, the relation between position x and time t is given by x^2 + 2x = t (here x>0). Choose the correct statement. In the one-dimensional motion of a particle the relation between position x and time t is given by x^2 + 2x = t (here x>0). Choose [...]

A 2 m wide truck is moving with a uniform speed v0 = 8 ms^−1 along a straight horizontal road. A pedestrian starts to cross the road with a uniform speed v, when the truck is 4 m away from him. The minimum value of v so that he can cross the road safely is [...]

Starting from rest a particle moves in a straight line with acceleration a=[2+∣t−2∣]m/s^2 Velocity(in m/s) of particle at the end of 4s will be Starting from rest a particle moves in a straight line with acceleration a=[2+∣t−2∣]m/s^2 Velocity(in m/s) of particle at the end of 4s will be October 18, 2020 Category: Arihant Physics by [...]

A car 2 m long and 3 m wide is moving at 10m/s. when a bullet hits in a direction making an angle of tan^-(3/4) with the car as seen from ground . The bullet enters one edge of the car at the corner passes out at diagonally opposite corner neglecting gravity , the time [...]

A horizontal wind is blowing with a velocity v towards north-east. A man starts running towards north with acceleration a. The time after which man will feel the wind blowing towards east is A horizontal wind is blowing with a velocity v towards north-east. A man starts running towards north with acceleration a. The time [...]

Acceleration (a)-displacement(s) graph of a particle moving in a straight line is shown here. The initial velocity of the particle is zero. The v-s graph of the particle would be Acceleration (a)-displacement(s) graph of a particle moving in a straight line is shown here. The initial velocity of the particle is zero. The v-s graph [...]

Four rods each of length I have been hinged to form a rhombus. Vertex A is fixed to a rigid support, vertex C is being moved along the X− axis with a constant velocity v as shown in the figure. The rate at which vertex B is approaching the x− axis at the momentum the [...]

A particle moves in space along the path z = ax^3 + by^2 in such a way that dx/dt = c = dy/dt where a, b and c are constants. The acceleration of the particle is A particle moves in space along the path z = ax^3 + by^2 in such a way that dx/dt [...]

A point mass starts moving in straight line with constant acceleration a from rest at t = 0. At time t = 2s, the acceleration changes the sign remaining the same in magnitude. The mass returns to the initial position at time t = t0 after start of motion. Here t0 is A point mass [...]
