What was Dan’s final velocity at this time?

Click For Summary
SUMMARY

Dan's final velocity after running a distance of 60 meters in 8 seconds is calculated to be 7.5 m/s. This is derived from the formula for velocity, where distance divided by time yields the final velocity. For acceleration, two calculations were presented: one yielding 0.9375 m/s² and another yielding 1.875 m/s², with the latter being correct under the assumption of constant acceleration. The discussions confirm that both calculations for final velocity and acceleration are valid, with emphasis on the correct application of the formulas.

PREREQUISITES
  • Understanding of basic kinematics
  • Familiarity with the formulas for velocity and acceleration
  • Knowledge of units of measurement in physics (meters, seconds)
  • Ability to perform basic algebraic calculations
NEXT STEPS
  • Study the equations of motion in physics, particularly for uniformly accelerated motion
  • Learn about the concept of constant acceleration and its implications
  • Explore real-world applications of kinematics in sports science
  • Practice solving problems involving velocity and acceleration using different scenarios
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding motion and acceleration in real-world contexts.

Dan starts from rest and started running for a distance of 6.0 x 10(power of 1) m in 8 s. [4 Marks]

a) What was Dan’s final velocity at this time?
6*10 = 60 -> 60/8 = 7.5
7.5m/s <-- is this right?

b) What was the acceleration of Dan?

7.5-0 divided by 8 = 0.9375
so 0.9375m/s squared

is question a and b right?... Can anyone please help me...
 
Physics news on Phys.org
Can anyone help me with this too please? thanks T.T
 
anyone...
 
11. a) 60m in 8 sec -> 7.5 m/s
b)d=60m t= 8 v(I)= 0

60m= 32a -> a= 60/32

acceleration -> 1.875 m/s squared

is it right?
 
(b) seems fine.. (assuming constant acceleration)
why don't you try for (a) in a similar fashion!
 
I think you had it right the first time for part b, part a looks fine. What is acceleration? Change in velocity over change in time right?
 
thankyou everybody
