A towed caravan, of mass 600 kg is attached by a ball hitch to a car. They are driven round a corner of 35 m radius. The coefficient of friction is 0.5 between caravan wheels and wet road. The centre of gravity of the caravan is 1.2 m above the road. Half the track (distance laterally between wheels) is 0.85 m. Calculate the maximum speed in m/s that the caravan can go round the corner without overturning or sliding.
A 1.7 kg block and a 2.3 kg block are attached to opposite ends of a light rope. Find the acceleration of the lighter block
A 2.40 H coil with a resistance of 3.95×10^2 Ohm is in series with a 4.86×10^3 Ohm resistor. What is the peak value of the potential difference across the coil
An automobile starts from rest and accelerates to a final velocityin two stages along a straight road. Each stage occupies the sameamount of time. In stage 1, the magnitude of the car's accelerationis 2.11 m/s2. The magnitude of the car's velocity ..
