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

Answer:

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

b) F = 40648.42N

Explanation:

We will use kinematics to calculate the average acceleration:

$a = \frac{Vf-Vo}{t}$

$a = \frac{26.3-0}{0.61}$

$a = 43.11m/s^2$

By dynamics:

$F = m*a$

F = 942.9*43.11

F = 40648.42N
