Answer 1

5sec times taken to travel 45.8 m when a roller coaster car is moving 1.98 m/s on flat ground when it begins to accelerate at 3.77 m/s².

What is acceleration?

The rate at which velocity changes with time, in terms of both speed and direction.

Using formula:

s = ut + 0.5 a$t^2$

45.8 = 0 × t + 0.5 ×(-3.77) × $t^2$

$t^2$= 2×458 × $\frac{100}{37}$  × 10

t = square root 24.2

t = 5sec

Hence, 5sec times taken to travel 45.8 m.
