Answer
a) See the detailed answer below.
b) See the figure below.
c) $x_1=7.34\;\rm m$
Work Step by Step
a) A kid plays with a toy car, he pushes it on a ramp tilted $10^\circ $ above the horizontal. The car was released at a speed of 5 m/s and it continues moving on the ramp until it stops.
Assuming that the friction between the toy car and the ramp is negligible, find the distance traveled by the toy car on the ramp.
b) See the graph below.
c) Solving for $x_1$;
$$x_1=\dfrac{0-5^2}{-2\cdot 9.8\sin10^\circ}=\color{red}{\bf 7.34}\;\rm m$$
