Question

Body rolls down an inclined plane having angle 30° with horizontal, its acceleration is: a).9.8m/sec b) 4.9m/sec c) 2.8m/sec? d) None​

Answer 1

Answer:

b) 4.9m/s2

Explanation:

a=gsinα

α=30°

a=9.8*1/2

=4.9m/s2

Answer 2

Answer:

4.9m/sec^²

Explanation:

a=gsin(30) | sin30 =0.5|

a=9.8×.5 = 4.9m/sec^²
