Acertain freely falling object, released from rest, requires 1.60 s to travel the last 29.0 m before it hits the ground. (a) find the velocity of the object when it is 29.0 m above the ground. (indicate the direction with the sign of your answer. let the positive direction be upward.)

-10.277 m/s

Explanation:

t = Time taken = 1.6 s

s = Distance travelled = 29 m

u = Initial velocity

a = Acceleration due to gravity = 9.81 m/s²

∴ Velocity of the object when it is 29.0 m above the ground is -10.277 m/s

which three statements are true about all alloys?

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
