Question

with an initial velocity 50 m/s a horse rider attains a maximum velocity 100m/s in 10 sec then find acceleration the rider?​

Answer 1

To Find :

The acceleration of the rider

Given :

• initial velocity , u = 50m/s
• final velocity, v = 100 m/s
• time, t = 10 s

Formula to be applied:

• acceleration = (v-u)/t

Solution:

given, initial velocity = 50m/s

final velocity = 100 m/s

time = 10 sec

so, acceleration = (v-u)/t

$\tt{ \implies \: acceleration = \frac{100 - 50}{10} }$

$\tt{ \implies \: acceleration = \frac{ \cancel{50}}{ \cancel{10}}}$

$\red{ \underline{ \boxed { \tt{acceleration = 5 \: m {s}^{ - 2} }}}}$

so, Acceleration of rider = 5m/s²

Additional information :

1] Equations of motion :

• a = (v-u)/t
• v = u+at
• s = ut + ½at²
• v²-u² = 2as

2] Other formulas :

• u = v-at
• t = (v-u)/t

Answer 2

Explanation:

initial velocity =u=50m/s

final velocity=v=100m/s

acceleration= v-u/t

100-50/10

50/10

5m/s

formula finalvelocity -initial velocity/time

I hope you understand motion
