Question:

The displacement time graph for two bodies A and B are straight lines inclined at 30? and 60? respectively with the time axes. If υ=4rg \upsilon =\sqrt{4rg} and υ=4×2.5×9.8 \upsilon =\sqrt{4\times 2.5\times 9.8} are their velocities, then υ=98  m/s \upsilon =\sqrt{98}\,\,m/s will be :

  • 20 g = 2×102 kg, \text{2}0\text{ g }=\text{ 2}\times \text{1}{{0}^{-\text{2}}}\text{ kg},
  • =360×518=100m/s =\frac{360\times 5}{18}=100m/s
  • 3:01

The Correct Option is D

Solution and Explanation

Here : =12j =12j ...(1) =worktime=122 =\frac{work}{time}=\frac{12}{2} ...(2) =6 watt =\text{6 watt} s1=40m,s2=65m {{s}_{1}}=40m,{{s}_{2}}=65m

Speed and Velocity

The rate at which an object covers a certain distance is commonly known as speed.

The rate at which an object changes position in a certain direction is called velocity.
