A particle covers half of its total distance with speed v₁ and the rest half distance with speed v₂. Its average speed during the complete journey is
A student measures the distance traversed in free fall of a body, initially at rest in a given time. He uses this data to estimate \( g \), the acceleration due to gravity. If the maximum percentage errors in measurement of the distance and the time are \( e_1 \) and \( e_2 \) respectively, the percentage error in the estimation of \( g \) is
A bus is moving with a speed of 10 ms⁻¹ on a straight road. A scooterist wishes to overtake the bus in 100 s. If the bus is at a distance of 1 km from the scooterist, with what speed should the scooterist chase the bus?
A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S₁ and that covered in the first 20 seconds is S₂, then:
