solve for me: Q1) In the Soapbox Derby in (Figure 1) , young participants build non-motorized cars with very low-friction wheels. Cars race by rolling down a hill. Assume that the track begins with a 49-ft-long (1 m = 3.28 ft) section tilted 12 below horizontal. -What is the maximum possible acceleration of a car moving down this stretch of track? -If a car starts from rest and undergoes this acceleration for the full l, what is its final speed in m/s? Q2) A boat takes 4.0 h to travel 32 km down a river, then 6.0 h to return. -How fast is the river flowing? Q3)A gray kangaroo can bound across a flat stretch of ground with each jump carrying it 11 m from the takeoff point. -If the kangaroo leaves the ground at a 19 angle, what is its takeoff speed ? -What is its horizontal speed?
