Fnet = -25N + 30N = 5N
(25N is negative since left is negative)
Answer:
a) 29.36 m
b) 2.44 s
c) 2.57 s
d) 25.117 m/s
Explanation:
t = Time taken
u = Initial velocity = 24 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
b)

Time taken by the ball to reach the highest point is 2.44 seconds
a)

The highest point reached by the ball above its release point is 29.36 m
c) Total height is 3+29.35 = 32.35 m

The ball reaches the ground 2.57 seconds after reaching the highest point
d)

The ball will hit the ground at 25.2117 m/s
Answer:
F = 236063.6N
Explanation:
Please see attachment below.
Answer:
Explanation:
Givens
m = 942
F = 6731
t = 21 seconds
vi = 0
vf = ?
Formula
F = m * (vf - vi ) / t
Solution
6731 = 942*(vf - 0)/21 Multiply both sides by 21
6731 * 21 = 942*vf
141351 = 942*vf Divide by 942
141351/942 = vf
vf = 151 m/s
