The answer is “Impulse acting on it” according to the impulse-momentum theorem.
Answer:
-2.5 m/s²
Explanation:
The acceleration of a body is the change in it's velocity with time.
The change in velocity with time can be obtained as the slope of a velocity time graph ;
Acceleration = (change in velocity / change in time)
Taking the slope :
Change in Velocity = △y = y2 - y1
Change in time = △x = x2 - x1
(10, 15) ; (0, 40)
△y / △x = y2 - y1 / x2 - x1 = (40 - 15) / (0 - 10)
△y / △x = 25 / - 10 = - 2.5 m/s²
Answer:
17.89 m/s
Explanation:
recall that one of the equations of motion can be expressed as:
v² = u² + 2as,
where
v = final velocity = given as 20 m/s
u = initial velocity = given as 7.0 m/s
a = acceleration. Since it is freefalling downwards, the acceleration it would experience would be the acceleration due to gravity = 9.81 m/s²
s = displacement (we are asked to find)
simply substitute the known values into the equation:
v² = u² + 2as
20² = 7² + 2(9.81)s
400 - 49 = 19.62s
19.62s = 351
s = 351/19.62
s = 17.8899
s = 17.89 m/s
