Why is it necessary to place arrowhead of the vector in the terminal point?
Just to signify that that exact point is the final or latest limiting point.
How do you find acceleration falling object with only speed and distance?
a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled
What is 370.2 divided by 10?
37.02
How do you round 7894.49372 to the nearest thousandth?
7894.494 thousandths is the third number after decimal point the fourth number after decimal point in this number is 7 is greater than or = 5 so round up so the final roudn up answer is 7894.494
What is velocity and speed?
Speed is a scaler quantity i.e. it has magnitude only without direction. It can be calculated using the formula : speed = distance/time where distance is the total distance travelled from initial position to final position; time is the total time taken to cover this distance. Velocity is a vector quantity i.e. it has magnitude as well as direction. It can be calculated using the formula : velocity = displacement/time displacement is the distance between final position & initial position; time is the total time taken to cover this displacement. for example: if a body starts from some initial point goes to a certain distance x and returns back to the initial position. So the total distance covered is 2x but displacement is 0 (zero) because initial & final position are same. So its speed is 2x/time while velocity is 0/t = 0(zero)
