answer:

The tape in Figure 2.7 was pulled through a timer by a

trolley travelling down a runway. It was marked off in

tentick lengths.

a What can you say about the trolley's motion?

b Find its acceleration in cm/s2

2 16 m in 45

3 with a uniform acceleration of 2 m/s2

Which statement(s) is (are) correct?

A 1,2,3 B 1,2 C 2,3 D 1 E 3

10 If a train travelling at 10 m/s starts to accelerate at 1 m

for 15s on a straight track, its final velocity in m/s is

A 5 B 10 C15 D20 E 25

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

i dont know but
