Question

ipanyng grapi. WHal is uie Speed of the (C) 6.0 m/s (A) 1.0 m/s (B) 2.0 m/s car at t = 3 10.5 m/s 5. An object is released from rest and falls a distance h during the first second of time. How far will it fall during the next second of time? Ayh (B) 2h (C) 3h (D) 4h 6 If a ball is thrown directly upwards with twice the initial speed of another, how much higher will it be at its apex? (A) 8 times (B)2 times (C) 4 times (D) 0.5 times The diagram below represents a toy car starting from rest and uniformly accelerating across the floor. The time and distance traveled from the start are shown in the diagram. 1.2 1.9 Start 6cm 54cm 96cm Os .1s 2s .3s 4s 7. What was the instantaneous velocity of the cart at 96 centimeters from the start? (A) 0.6 m/s (B) 4.8 m/s (C)1.9m/s (D) 60 m/s (E)2.4 m/s

Explanation / Answer

5)(c)3h

explanation

since, d = 1/2 g t^2

d' = ut + 1/2 at^2

5)(c)4 times

explanation

H = v^2/2g

h1 = 1/2g = H

H2 = 2^2/2g = 4H

6)(e)2.4 m/s

explanation

v = d/t = 0.96m/0.4 = 2.4 m/s
