Question

Initial velocity of a partial is 8i^+4j^ and acceleration is -2i^ ,then after what time velocity will be perpendicular to initial velocity

Answer 1

Answer: Following steps may help you to solve the given problem.

Step 1 . Consider that required condition is fulfilled at time t then find the velocity at that time by using equation of motion.

Step 2. if the velocity at the required time is perpendicular to the initial velocity then the dot product should be zero. so calculate the product of the velocities and then equate it to zero you will get the value of time.

You can refer to the attachment if you want to see the solution.

∆ On doing all this you will get t is equal to 3 seconds
