Please help

Mease help me solve : $1 -5.00cm= (2.91cm) + (11 (c3) ) (3.05)+ z a (3. 05) 2 ? cm/sz along a * A record of travel straight path is a follows : . Start from rest with constant acceleration of 2.15 3 2 For 17.0 s. . Maintain constant velocity for the next 2.10 min . Apply constant negative acceleration of - 9.14# for 40s A) Total displacent for the trip ? B) Average speed For leg 1, 2 and 3 , as well as the complete trip ? legd m/s leg z m/s leg 3 - m/s complete trip -m/s * Tennis player tosses a tennis ball stright up s then catches it after 1.90s at the same height as the point of release . A) Acceleration of ball in flight ? mayritude m/s 2 direction my or 8 B) velocity of ball at maximum height ? magnitude m /s direction a Initial velocity of the ball ? m / s 2 upward D) Maximum height it reaches -m
