Aboy throws a snowball straight up in the air with an initial speed of 4.50 ft/s from a position 4.00 ft above the ground. the snowball falls straight back down in to a 6 inches of snow. the snowball feels a deceleration of 100 m/s2 upon impact with the snow bank before coming to rest. (a) when does the snowball hit the top of the snow bank? (b) how far from the ground does the snowball come a rest?

a) 0.658 seconds

b) 0.96 inches

Explanation:

Time taken by the ball to reach the highest point is 0.14 seconds

The highest point reached by the snowball above its release point is 0.315 ft

Total height the snowball will fall is 4+0.315 = 4.315 ft

The snowball will reach the bank at 0.14+0.518 = 0.658 seconds after it has been thrown

The snowball goes 0.5-0.42 = 0.08 ft = 0.96 inches

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
