Question 1. Two tourists who are at a distance of 40 km from their camp must reach it together in
shortest possible time. They have one bicycle which they decide to use in turn. One of them started
walking at a speed of 5 km/hr and the other rod of the bicycle at a speed of 15 km/hr. The tourists
agreed to leave bicycle at intermediate points between which one walks and other ride. How long
bicycle remain unused:
(A) 5hr20 min
(B) 2hr40 min
(C) 1hr10 min
(D) 55 min
Ans - B
Question 2. A particle starts moving with initial velocity 3 m/s along x-axis
√ from origin. Its acceleration
is varying with x in parabolic nature as shown in figure. At x = 3√m tangent to the graph makes
an angle 60◦ with positive 𝑥-axis as shown in diagram. Then at 𝑥 = 3
q√
(A) v = ( 3 + 9)m/s
(B) a = 1.5 2
√ m/s
(C) 𝑣 = 12 m/s
(D) a = 3 m/s2
Ans - AB
Question 3. An object can move along a straight line with constant acceleration 2 m/s2 . The total
distance used in the event where speed of object changes from 8 m/s to 4 m/s in shortest time is
5 × n. Find n ?
