The coefficient of friction of the box (m = 183 183 kg) and μs = 0.15 between the car platform 0.15 . Specify the shortest time for the car to reach speed 60.0 km / h without the box sliding on the car platform?
What is length contraction
a uniform rod AB of length a and weight w is freely hinged to a vertical wall at A and is maintained in equlibrium by a light string of lenght a fastened to B and to a point C at a distance b vertically above A. prove reaction at hinge WSqrt(a2-2b2)/2b and find tension in the string
A shot fired with velocity u at elevation theta hits a mark at a distance R in the same horizontal plane. If there is no air resistance, show that (u2/g)f(theta).
A cat chases a mouse across a 1.2 m high table. The mouse steps out of the way and the cat slides off the table at a speed of 7.0 m /s. Where does the cat strike the floor (horizontal distance from table leg)?
Explain the geometrical interpretation of the divergence of a vector field A(x,y,z).
A projectile is lunched with 30m/s at an angle 60 degree with the horizontal. Find the position of the projectile and the magnitude and direction of its velocity at t=2s
A 1Kg object is tied with a 2m rope and making uniform circular motion on the horizontal surface. the coefficient of friction is 0.2. if the rope can succeed maximum tension of 20N, what is the maximum velocity of the object
A flywheel of rotational inertia I = 53kg⋅m2 rotates with angular speed 4.0 rad/s. A tangential force of 6.5 N is applied at a distance of 0.36 m from the center in such a way that the angular speed decreases. How long will it take the wheel to stop?
Result: 100 s
A stationary tyre begins to rotate at constant angular acceleration to reach an angular velocity of 12.0 rad/s in 3.00 s. Find (a) the magnitude of the angular acceleration of the tyre and (b) the angle in radians that it rotates during this time interval.
Result: (a) 4.00 rad/s2 (b) 18.0 rad
