Question

6.Ifthe velocity of the car increases from 10 m/s to 15 m/s in 10 sec, then
the acceleration is
O (2), 0.5 mg
(a).0.5 m/s2
O
(b) -0.5 m/s2
0
(0) 0.2m/s2
0
(d) -0.2m/s​

Answer 1

Answer:

0.5 m/s^2

Explanation:

acceleration = (final velocity- initial velocity)/time

=

$\frac{(15 - 10) \frac{m}{s} }{10s} \\ = 0.5 \frac{m}{ {s}^{2} }$

So option a is the correct one.

Answer 2

Answer:

(a) 0.5 m/s² is the acceleration.

Explanation:

v = u + at. ( Newton 's first equation)

15 = 10 + a ( 10)

15 - 10 = a 10

5 = a (10)

5/10 = a

0.5 m/s² = a

Hope it helps.
