Given the following speeds versus elapsed time, for a 1000 kg object accelerating horizontally with constant propulsive power and negligible friction (hint - plot KE vs time & notice units of Joule vs kJ)

Time (s) t0 = 0, t1 = 1, t2 = 2, t3 = 3, Speed (m/s) V0 = 5.66, V1 = 8.00, V2 = 9.80, V3 = unknown

The propulsive force at time zero is _____ (kN)

Given the following speeds versus elapsed time, for a 1000 kg object accelerating horizontally with negligible friction and constant propulsive power such that applied work on the objectis power x elapsed time. Instantanous power is defined as force x velocity. Hint: the kinetic energy at time zero is 16 kJ. Time (s): t0=0, t1=1, t2=2, t3=3, Speed (m/s) V0= 5.66, V1= 8, V2=9.80, V3=unknown. The acceleration at t1=1 s with V1=8 m/s is, a3= ____________ (m/s^2). I will rate if...
