An electron moving with a velocity 50000 m/s enters into a uniform electric field and acquires a uniform acceleration of 10000m/s² in the direction of its initial motion. The time in which the electron would acquire a velocity double of its initial velocity.

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
