Question

A particle experiences constant acceleration for 20 seconds after starting from rest. If it travels a distance D1 in the first 10 seconds and distance D2 in the next 10 seconds then, (a) D2 = D1 (b) D2 = 2D1 (c) D2 = 3D1 (d) D2 = 4D1 10. An electron moving with a velocity of 5×10*3m/s enters into a uniform electric field and acquires a uniform acceleration of 10*3m/s*2 in the direction of initial velocity. i. Find out the time in which electron velocity will be doubled.? ii. How much distance electron would cover in this time.? 11. A train 100 m long is moving with the velocity of 72 km/hr. Find the time it takes to cross the bridge which is 2 km long? 12. The distance moved and the magnitude of displacement are equal in ? (a) The earth is revolving around the Sun (b) Object moving in circular path (c) The pendulum is moving to and fro (d) Object moving on straight road 13. An object travels 20 m in 2 s and then another 16 m in 2 s. What is the average speed of the object?
