Question

A dragster and driver together have mass 942.9 kg . The dragster, starting from rest, attains a speed of 26.3 m/s in 0.61 s. Find the average acceleration of the dragster during this time interval. Answer in units of m/s 2 . lawson (al52364) – forces – szymczak – (41202) 4 032 (part 2 of 3) 10.0 points What is the size of the average force on the dragster during this time interval? Answer in units of N.

Answer 1

a)
`a = 43.11m/s^2`

b) F = 40648.42N

Step-by-step explanation:

We will use kinematics to calculate the average acceleration:

`a = (Vf-Vo)/(t)`

`a = (26.3-0)/(0.61)`

`a = 43.11m/s^2`

By dynamics:

`F = m*a`

F = 942.9*43.11

F = 40648.42N
